Hi, Does anyone have any real-world thoughts to share on the performance of the C4S at 50'? Particularly in regards to 40m? Also, interesting: C4S at Texas Towers, $629 US ($850 Cdn). C4S at Radiowor
Is Raibeam still in biz? I see there Web site is active, but e-mails are bounced for unknown user. Anyone try them? Particularly the triband version. (Steve, was the Raibeam in the tribander report?)
Regarding coaxial cable: unless I had extremely long runs, or had excess monetary capacity, I think it's pretty hard to beat brand-name RG-213 for most HF applications. Flexible, UV resistant, centre
It seems to me that the issue here is not the design of towers or the ratings of same: it's of operator error in poorly planning the construction of his crank-up tower and then leaving it up during c

Sorry, sent a blank one somehow by accident... I would suggest Tom's statistical conclusion that these don't prevent strikes is backed up by the physics of a lightning strike. The two poles, as it we
Hi Jim, So I just went through Rob's slide show. Seems to me he filled it with enough technical information to impress the pants off a patent inspector or radio newbie, but I'm not sure he has reinve
Hi Tom, I nussed this message in Sept. and just came across it browsing the archives. http://www.hamuniverse.com/1elbeam.html So by his definition, then, an inverted vee will have gain straight down!
I wonder how many critics of this picture have actually seen the picture and how much of this thread has been fuelled by nothing more than hearsay or hatred of the ARRL. It's a tiny little thing, 1 c
There is in the ARRL handbook a design for an end-fed dipole just like Tom suggests. It was oriented horizontally, but I see no reason why vertical orientation wouldn't work. The antenna was made of
Isn't it one of LXC's tips to order 4,000 psi, which cures to 3,000 psi rather quickly? I forget the exact times, but it seemed that ordering stronger concrete than you need shaved considerably the w
Hmmm, Aside from wondering about anybody who can't be bothered to read his ad before posting it, this product looks an awful lot like Radioworks' T4 Line Isolator, the most expensive of which is $43.
I'm a little confused by Martin's question. I thought the whole idea behind an SPG was to not only MAKE SURE the two grounds were connected, but to eliminate the distinction. Have I missed something?
Here's another reason why someone might choose fixed elements, price. I don't mean to disparage the SteppIR, it has a lot going for it, but consider that the 4-el SteppIR is $1,745. The C3E is $735,
No doubt, but please remember the original question: why would someone choose a fixed-element design over the SteppIR? Cost is certainly a factor. If one is happy with the tradeoffs going with the C3
Roger, VE3ZI, added: tuned moved Hi Roger, Thanks. I wonder, though, if you weren't disappointed with the elevated AV3 because of insufficient decoupling between either the pole (if it was metal) or
It's a legitimate question, one that could help someone determine which product to buy. Twelve seconds for a one-way band change isn't a huge issue, sure, but 24 there and back (moving multipliers, e
Hi Bill, I think you may be misunderstanding a quad antenna: A quad element is not a bent dipole or a shortened element in any way. It is a full-wave loop, an antenna that by itself exhibits gain ove
