I had something like that, from E-Z Way, many years ago. We used to call them "ham killers," but that's a long story! -WB2WIK/6 "If everything seems under control, you're just not going fast enough."
Hi Jos, I'm all for it, and recommended this already. I don't have the bandwidth for such a project myself, nor am I a mechanical engineer; however I'm certain such expertise exists, possibly right h
I think the responsible manufacturers don't make any ridiculous claims about gain. Tennadyne, for example, rates the T6 (12' boom, 6L 14-30 MHz) at 5.1dBd and BW = 57 degrees, and it's very much bigg
Hi Josh, I didn't know Tennadyne even made a 20m-only log yagi. The only antennas on their website are the T6 through T12 and one VHF-UHF model, nothing monoband. I don't think a 3/8-wavelength boom
Interesting, Josh. I've been a real believer for many years that one can never evaluate the performance of any antenna, if it's the only one he has. Any antenna is "terrific," when it's the only one
[Steve Katz] Nope, I have zero problems with either my TS-850S/AT or my TR-7 in this regard. Neil, K6SMF, is 0.7 miles from me with long-boom monobanders up 70' to 90' on all HF bands (except 80m),
[Steve Katz] Jos, when cost is no object, all sorts of things are possible! I worked on the AWACS program in the late 1970's and that was a "cost plus" contract from USAF. The more it cost to build,
The actual article to which ZL1DD refers is in the May 1979 issue of Ham Radio magazine, and entitled, "Quads vs. Yagis Revisited," by Dr. Wayne Overbeck, N6NB. A photo from that article, and a littl
If it has to take very high winds and you don't want to be servicing it, a commercial (as opposed to amateur) VHF beam might fill the bill better than what we normally use, because the big-name VHF a
This subject's been beated to death before, but I also subscribe to the "no pin" theory of Advanced Avoidance of Rotor Replacement. I can realign my beams in fifteen minutes, but swapping out the rot
This is not a very useful comparison, especially today, considering how long W2PV's been dead. I might as well discuss how well W6AM did with nothing but wires... -WB2WIK/6 "If everything seems under
Mirko, At the same time, if you recall, how loud was N2AA? Even farther (hundreds of miles) to the south, but still in the northeastern U.S., relatively speaking. WB2WIK/6 "If everything seems under
Interesting subject. I'm sure this varies a great deal, but I measured the resistance from the top to the bottom of 70' of R25 that had been up for a couple of years, and it was very high. (Measureme
[Steve Katz] Actually, my DVM uses 4.5V. At 20 Ohms, that's 225 mA through the circuit. Still, not very much. Your suggested experiment might be useful, I'll try it next time -- although the 70' R25
Oh, geesh...that piece of junk still around? It's "all solid state," alright. It's a toroid and a dummy load built into a metal case, as the ARRL determined when they X-Rayed it. Cost to build: Proba
You guys are so negative! The Maxx-Com requires no power because it's powered by RF, which is dissipated internally creating thermal rise; that thermal rise is used to spin fan blades which drive a r
[Steve Katz] I was just using a Simpson analog meter which provides a current from a source having 4.5Vdc potential. When measuring 20 Ohms resistance, the resulting test current is >200 mA. Still,
