As of today, Friday the 11th it's $23.40 USD with a 1.17 Euros per USD. That's a pretty good contribution. Roger Halstead (K8RI and ARRL 40 year Life Member) N833R - World's oldest Debonair CD-2 www

Cable radiation, anyone? I've yet to see a review of a CFA/EH that demonstrated the reviewer understood that possibility, took serious precautions against it, and then measured it. Lacking all that,
Is it "written" someplace that he has to use the entire span for the active antenna??? No, but I have already tried reducing wire length to see if this was a possiblity. A shorter wire results in les

Having read Tom's comment about the 2m loop antenna in QST, I went and looked at the article. Back in the 'good ole days' of 2metres, when everything was horizontally polarised AM, and a mobile rig u
Ward, Thanks for chiming in with the "data comm" metaphor. One thing that I have had to accept in my (too) many years of hanging out in the electronics industry is that people tend to accumulate know

Then he and his assistants missed a very basic point at the root of what causes radiation. This goes along with my viewpoint. We are losing the basics. If they had a grasp on basics or a good feel f
NVIS means "Not all we hear about anyone want to work DX The letter writer had the NVIS antenna in the correct application. He wanted to use high angle skywave. He just was clueless about groundwave

Jim, Thanks for going through those calcs, it's much appreciated. Just a couple of questions: Why did you choose 60% guy anchors instead of the commonly recommended 80%? I agree though that 60% is pr
OK... some real numbers.. off the Rohn BX data sheets which I found on the web. Whether or not this is a tower anyone would actually use, or contemplate guying is sort of immaterial. It's representat
There down You Well, it's a heck of a lot easier to climb a ladder propped against the (unextended) tower carrying a few bolts and a wrench than carrying a multiband beam antenna. One might contempla
Climb a tiltover to latch the beam hinge ... kinda defeats the purpose, eh? ;-) Perhaps an electrically, or mechanically (pull string), powered latch might solve that problem? -- Thanks! & 73, doc k

Tom, Are you saying that it is not possible to decouple with a coaxial sleeve such as is commonly used on VHF or UHF collinear antennas ? It was used for many years quite successfully as a quarter wa
