Message-ID: <11MJg.39363$NF3.33013@trnddc05> Date: Fri, 01 Sep 2006 01:28:29 GMT The technical aspects of antennas are complex, and some of the readers of this group (such as myself) are unable to fully participate in discussing the fine points. I want you to know that your dad was one of the handful of highly respected antenna gurus who discussed these technical issues. I learned very much by reading his posts and thinking about his views. The newsgroup will not be the same without him. Wayne "Penguin" wrote in message news:1157040328.531086.156050@m79g2000cwm.googlegroups.com... > Many thanks for all the kind words about Reg.

Subject: Flexible Coax for HT instead of remote Mic Date: Thu, 31 Aug 2006 21:36:13 -0500 Message-ID: I'd like to use my HT in the car. I figure why should I buy the remote microphone when the HT itself is the size of a microphone. All I need is coax that is flexible enough to withstand the rigors of a mic cable. Anyone know of a source of flexible coax? (I have a few feet of Columbia Super-Flex RG-58, but it's 35 years old and really beat up. Do they still make it?) -- Bob D.

I know I can use a transformer on 20m, but I figure I'll save my ferrites if I'm building L networks anyway, and to be economical of junkbox parts, I'd also like to save my air variables. Would capacitors made of PC board be decent transmitting caps at these frequencies, provided they didn't break down? The board is hamfest surplus special... so I don't know what it is, but it may be G10... it's a dark green fiberglass material, about 2mm thick dielectric. Comparing the capacitance of a 2 inch square of the material (88pF) to a parallel plate cap with air dielectric of the same physical dimensions (12pF) gives a dielectric constant of about 7.3. I'm going to try it anyway, but I'd appreciate any input anyone has about the suitability of unknown PC board as HF transmitting capacitor material, primarily with respect to dielectric losses. If it matters, the 20m network is a 1.14uH series inductor with an 88pF capacitor shunting the antenna side. The 17m network is a 3.08uH series inductor with a 29pF shunt. The 20m antenna impedance is about 250+j0 and the 17m impedance is about 950+j1200. I figure there might be some voltage breakdown issues, but worst case, I smooth the edges of 2 or 3 2x27pF or 3x27pF caps and put them in series.

I'd consider _that_ a plus. Helps rein in the motor-mouths. What the OP needs to be concerned about is not so much the flexibility of the feed line, but, rather, the sturdiness of the coax connector at the HT. That 'joint' will take a lot of stress in such a mode of operation. Not only will there be problems at the point where the coax enters the male connector, but the large stresses on the female connector will oft times ruin the internal attachment to the pc board. Back before the banality of VHF FM operations drove me away, I would make up a little plastic 'back-board' that attached securely to the HT and extended up a ways to help support the coax. As well, I slipped some over-sized tubing over the coax to move the flexing away from the coax connector.

References: Message-ID: Date: Fri, 01 Sep 2006 10:10:46 -0500 Hi Bob There isnt a simple answer to your question! You havent really defined what "usable" really means either. As a gut feel however a discone would probably be "usable" over a 10:1 frequency range (say 44-440MHz) There will be some tradeoffs however, the most troublesome (in my view) being non optimal radiation pattern as you go higher in frequency. (ie the antenna pattern tends to sky) It will never work as well as an antenna designed for a specific frequency. Your only real option is to try it and see. Below about (say) 20MHz you'll probably get better performance just using the feedline to the discone. You might even consider separately RF earthing the R3 and then only connecting the centre conductor of the discone coax. You will of course encounter local noise issues but it does work. Its a hard call to find an antenna to do what you want unless a lot of compromises are accepted. If I was in that situation I'd probably grab one of those motorized car radio antennas type designs so I could adjust the length remotely, or look into some kind of (remote adjust) magloop design for at least the HF end.

Especially if you trim the copper back a bit from the board edge, it shouldn't be a problem. The 17M case is about 500VRMS at 100 watts. Even that probably won't be a problem. (I have an SO8 IC in front of me that claims to be OK with 600 volts between adjacent pins: less than half the thickness of your board.) Since the board area is so small for that 29pf, why not just try it? The thing I'd be most worried about is corona at the sharp edges of the board. If you were to make the capacitor plates circular, that would help. In addition, if you soldered a ring of, say, 12AWG bare copper wire to the edge of the circular plate on each side, that would make a rounded edge. If one side of the capacitor is "ground" anyway, just leave that side's copper the size of the board, and trim back only the other side. The outer edge of the PC board copper circle would just touch the "donut" of copper wire. A cap like that would probably be good for several thousand volts, assuming the dielectric extended out several mm past the circle. Fiberglass-epoxy isn't the best dielectric for a capacitor in terms of high frequency loss, but should be OK for your low power. But is it really standard fiberglass-epoxy? If it's standard 1.6mm thick, I'd expect no more than about 70pF with 4 square inches of plate area. A relative dielectric constant of 7.3 is too big for standard FR-4/G-10 material. You may need to put some RF current through it to test to make sure it doesn't heat up too much. I really don't think you'll need to put caps in series to get what you want. In any event, instead of making three separate capacitors, you could just add an air gap between two pieces of your copper-clad material...or use some dielectric other than air if it's easier. But some nylon screws and nuts (the nuts acting to space the boards), or even steel ones out on the periphery away from the capacitor plates, should work fine. You could even make it adjustable that way, by adjusting the spacing...

I've also found that HTs are less than ideal for mobile ops for another reason - squelch. Most of them do not have a separate squelch knob - you have to go through a menu to change the squelch setting. Not a good thing to do while driving - it's the sort of thing which makes J. Random Cellphone User's distracted behavior seem downright civilized. Add to this the fairly wide-open nature of most HT's RF front ends, (and the resulting sensitivity to intermod), and the amount of 2-meter RF noise and birdies from cable leakage, etc., and you end up with a bad mixture. An HT with a magmount antenna will do in a pinch, but I don't feel that it's a good long-term frequent-user solution in an urban area. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads!

Major issue is dielectric losses. As you know the antenna impedances, you are able to calculate the apparent power for the capacitor (just Ic*Uc [rms values]). Both Epsilon and loss factor for FR4 varies (depending on the manufacturer). You can use 0.01 as a rule off thumb. So if your capacitor "consumes" an apparent power of 500W (at 100W input), the loss inside the capacitor is about 500*0.01 = 5W. I hope this will help you.

He IMPLIES and ALLUDES to things but hardly ever states anything outright and then never with any referencible sources that anyone can access. Robeson has tried to construct an edifice, indeed almost a temple in which we should all venerate his mighty accomplishments AND, at the same time, has leveled barrages of personal insults and deragatory accusations against all challengers. That latter action negated his mighty constructs and established his fraud. That 'edifice' has to be torn down...if for no other reason than being an eyesore to us in his field of dreams. >>> > The duties of the Tennessee STATE Guard (not affiliated with >>> > the National Guard) were described by them as a sort of >>> > in-Tennessee 'custodian' of NG facilities if and only if the >>> > NG there is activated into federal service plus being a sort-of >>> > 'military police' for that state.

Part of that is the ever-present "conspiracy theory" coupled with some kind of imaginative armageddon scenario of a doomed future where everything in a state is in ruins or anarchy but the "state guard" can step in and "restore order." The curious thing about the latter is that some of the Believers in the efficacy of morsemanship think in the same manner...that only amateur radio survives the worst emergency and that only morsemanship can be used to call for help. That is patently absurd in light of reality but founded on the mythos of morse that grew following the Titanic disaster of 94 years ago. As to fully-activated National Guard units, the states have various plans to keep the NG structures and land intact, usually using civilian personnel (law enforcement, probably) and that does not require a lot of personnel. In the field of communications for the REAL public safety agencies, those agencies are well-supplied with many forms of communication of their own (outnumbering amateur licensees according to EIA data of about 15 years ago) that is NOT part of the "telephone infrastructure" that many ham-patriots erroneously think "always fails in an emergency." Most public safety agencies in the USA have established emergency-scenario plans and they periodically train/drill for those procedures. Very few amateur radio local organizations do that. >>> > >> >A well know amateur radio outlet had the owners daughter's photo >>> > >> >featured in a prominent amateur radio publication.

It was a waste of time when the macho middle-school mental-adolescents came in and talked trash and filth to anyone. How many of those anony-mousies were actual amateur radio licensees is unknown and irrelevant. The known licensed amateurs just didn't do anything about them. That presents a very BIG negative on the amateurs' ability "to police their own." They couldn't. They can't despite their brags about such "policing." Robeson once made claims that he was IN one of the local Los Angeles HRO stores, with "friends while visiting them." A big problem with that was that was his claimed time-line and NOT being able to describe, even in minor detail, the locations or the surrounding territory. The first HRO in northern L.A. was in Van Nuys, CA, in the center of the San Fernando Valley. [bought my Icom R70 there years ago] That HRO moved to Burbank, CA, a few years ago, at the corner of Buena Vista and Victory (a major intersection with shops at all four corners). It is across the street from a relatively new food supermarket having a huge elevated sign visible from all four corners. Robeson could not describe that sign, let alone the location, even though it was easily visible (he didn't name the supermarket). It is very familiar to me since my wife and I shop there regularly. Robeson couldn't name a single store in the mini-mall across the street from the market even though there's a Radio Shack outlet next to that HRO. That HRO has now moved again (they had a window sign announcing that for weeks) and we will see if Robeson wants to repeat all of his lies about being in any one of them. :-) >>> > Robeson imagined himself to be a "real" GSgt, a DILL sergeant >>> > who GIVES orders and is immune to any criticsm. :-) > >>> Sorry Anderson Amateur Radio >>>IS NOT<<< Boot Camp! > >> Guess the wannabe DILL sergeant told me, huh? :-) > >well real boot camp would pleasenter than what Robesin would devise > >I know Boot camp was accuauly the most fun I had in the army Brian and I were being sarcastic about "boot camp." The US Army and the USAF *never* had "boot camp." In those branches is was called BASIC TRAINING. It still is and is usually referred to familiarly as just "Basic." I "took Basic" at Camp Gordon (now Fort Gordon) which was in 1952 a Signal Corps center and now THE Center for Army Signal Corps. We had to learn basic infantryman soldiering, how to "close with the enemy and destroy them." No fun in that part of Georgia near Agusta. The only communications taught in Basic were courier duties and connecting/using an EE-8 Field Telephone plus laying field wire (real grunt work carrying that auto-pay-out wire box on a back pack). After 8 weeks of Basic we were assigned to Signal Schools...Field Radio and TTY at Gordon, radar-microwave-photography at Ft. Monmouth, NJ. For me, "fun" didn't begin until Monmouth and the ability to actually handle radios, examine their guts and theory, use them on the air. Things have changed greatly in military communications since 54 years ago. The Field Radio MOS long since became extinct and with it the need to learn manual radio- telegraphy. HF radio is still taught but more as an adjunct to VHF radios common from small units to battalion level...the SINCGARS family of digital voice/data, optional frequency-hopping and encrypted modes with a quarter million produced since 1989 and all operational...to be replaced soon with a compatible but upgraded family of radios with more and better features. HT-sized SINCGARS-compatible radios are being used in Iraq and Afghanistan now (you can see them on news telecasts). The ONLY radiotelegraphy classes are centered at the Military Intelligence School at Ft. Huachuca and that for (passive, listening-only) Intercept Analysis purposes, not communications. Some non-active or never-serving morsemen in here have insisted that Special Forces "use" radiotelegraphy since a Special Forces Communications Sergeant MOS is required to know that. Special Forces are very macho in image but they, like the USN SEALs, are a very small group of specialists, for (as their name implies) Special operations. The major Army and land-force marines effort is done by regular land soldiers. "Behind the lines" (quaint euphemism) comms can be done by regular land signal units by encrypted data over VHF-UHF, relay by aircraft or satellite, extemely hard to intercept. Even in the 1990 First Gulf War there was no "CW" used from "Behind enemy lines." The AN/PSC-3 did that or, in a few locations inside Iraq, by VHF voice or data. The extreme mobility of USA land forces now, and in 1990, is described in the many land-forces reports done on the First Gulf War, namely Operation "73-Easting." The final hundred hours of the First Gulf War outdid the best panzerfaust actions of Rommel in North Africa of 1942- 1943. About two orders of magnitude better. One thing that the American military did copy from Rommel's units was "Nevis" or NVIS, Near Vertical Incidence Skywave, short-distance ionospheric bounce that some hams deride as "cloud burning." Nevis works rather well and has been a field procedure in USA-USMC-USAF land-to-land comms for at least a quarter century. World War 2 was over 61 years ago. Vietnam War was over 33 years go. The First Gulf War started (and finished almost as quickly) 16 years ago. The Korean War went into a state of perpetual Truce 53 years ago. Amateur morsemen still gorge their imaginations on the Titanic disaster CW comms of 94 years ago. Time has gone on and technology has changed...for all but those hidebound morsemen are still pipe-dreaming their imagined glory and self-steam after watching old WW2 movies on late-night TV, demanding that future amateurs learn morse to defend their homeland. :-) LenAnderson@ieee.org Article: 229305 of rec.radio.amateur.antenna From: Cecil Moore Subject: Re: Mismatched Zo Connectors References: <1156572081.303410.216040@i3g2000cwc.googlegroups.com> <1156695436.006186.215170@p79g2000cwp.googlegroups.com> <1156785256.069644.201200@75g2000cwc.googlegroups.com> <1156792713.040407.124420@h48g2000cwc.googlegroups.com> <1156811317.904136.25960@h48g2000cwc.googlegroups.com> Message-ID: Date: Fri, 01 Sep 2006 20:49:23 GMT Jim Kelley wrote: > Or maybe it was just too hard for you.

If you change the source to a Thevenin equivalent 141.42V and 50 ohm source impedance and specify Z=50 ohms feedline impedance then the problem becomes solvable. The answer is that 200 joules exist in the feedline and, contrary to what W7EL states, will dissipate in the source resistance after the source voltage goes to zero.

Hi Owen, That information has been considered a secret that is vital to the interests of the United States of the Republican Party and is on the list of items not allowed on board airplanes, nor to be transported by skateboard across the border of any state contiguously bordering Texas, except Venezuela.

Oh well, it was worth a try. What I didn't add, was that you may need to be a chemist to work out what the components are, or to use Dave's hints and work out what is in it that produces those combustion products. I was just chatting with a friend who lugged his 2m gear up on a mountain top here in the national capital to work some AE DX. A newspaper reporter noticed him and came back with camera to do a story. I don't know if the public will understand that although he is using directional apparatus to bound electromagnetic radiation off passenger aircraft, that it is truly safe for all involved. Wait a minute, no one has been able to prove radio frequency EM radiation to be safe, have they?

But Jim said the XMTR was putting out 100 watts into an infinite load during steady- state, obviously an impossible mental boundary condition. A Thevenin equivalent circuit will supply 100 joules/sec into the feedline and then stop supplying power. That is not an impossible mental boundary condition.

With regards to your example, no correction to antenna theory is necessary. Small antennas can be efficient radiators, but the smaller the antenna, the more difficult to achieve reasonable efficiency. Antenna theory is well established. When you know the current distribution in a structure, one can calculate (mathematically or numerically) how much power is radiated (and also how much power is dissipated in the structure). This approach is used by virtually all Antenna Design software packages. All electrically small antennas have one thing in common, the usable bandwidth is small. The Q-factor of a lossless electrically small structure is proportional to about 0.05*lambda^3/Volume. For example a small loop of thin material with infinite conductivity has higher Q-factor than a loop of same diameter, but made of very wide strip (with infinite conductivity). The last one occupies more volume and therefore has lower natural Q. The Q-factor of practically small antennas can be that high that the bandwidth may by just a few kHz. The problem is in the matching. Matching, for example 0.8 Ohms in series with a reactance of 2800 Ohm (Q=3500), to 50 ohms is not easy. The Q-factor of the components is not high enough, some or most power is dissipated in the additional components, or even the antenna wire itself. So in the end your antenna may have an overall efficiency of 5% (-13 dB). Also voltages can be that high that power is lost by corona effects. Often, due to the high local E- and H-fields, power is lost in nearby constructions. About the practical use of small antennas. In many cases received signal levels are in the S9+20 dB range. As the noise level is far below this, loosing 13 dB (so your signal level will be S9+7 dB), is acceptable. If not, you may increase the input power. In the end, the small inefficient antenna is at least better then no antenna. So in my believe, a nice QSO over 600 km with a small antenna, doesn't prove that antenna theory has to be revised. I'm very curious to see the construction details. Best regards, Wim PA3DJS.

As the problem was stated, I have NO reason to include 100 joules in the set of correct answers. I also have NO reason to exclude 100 joules from the set of correct answers. If Jim had specified that the forward power and reflected power in the one-second long lossless stub was 50 watts each during steady-state, then we could conclude that there is 100 joules in the feedline. -- 73, Cecil http://www.qsl.net/w5dxp Article: 229345 of rec.radio.amateur.antenna From: Cecil Moore Subject: Re: WHAT'S IT MADE FROM ???

Is one on the input of a tuner and another on the output of the tuner? Those two forward power readings can be wildly different. So are SWR meter readings.

What textbooks say that? EZNEC says that a 3 meter tall monopole has a maximum gain of 1.5 dBi on 160m while a 38 meter 1/4WL monopole has a maximum gain of 1.36 dBi. In other words, they radiate approximately equally well both with high radiation efficiencies. The problem is not with the antenna's ability to radiate. The problem is in getting the RF energy into the antenna. The problem is not with losses in the antenna. The problem is finding an efficient j2250 inductor for the matching network. If we knew what your matching network looks like, we could estimate its efficiency. -- 73, Cecil http://www.qsl.net/w5dxp Article: 229349 of rec.radio.amateur.antenna Date: Sat, 02 Sep 2006 10:50:27 -0400 From: Mike Coslo Subject: Re: WHAT'S IT MADE FROM ???

Wonder how > Mr Goore would address this problem? > Diapers for cows perhaps? (grin) Methane, Dave. I won't say that global warming is happening or not. However, the science is sound regarding CO2, methane, and other gases that tend to retain heat in the atmosphere. The relationship between these levels and heat retention is fact. Perhaps there are mitigating factors going on. Perhaps ocean life can sequester the excess CO2, perhaps something else? Instead of picking on "Mr Goore", perhaps you folks that know better can provide scientific evidence of the mechanisms that are countering the so called "greenhouse effects. 8^) > Back on topic however, when you get back to the office > next week, just place a call to the mfgr of the product and > ask him to FAX or e-mail you a .pdf file copy of the > Product MSD
