The antenna and assembly manual look great. However, there is a technical error on page 8. The clamps are installed backwards. FWIW... The way I was taught to install these clamps was to remember the
Merlin, You idea should work just fine, although 205" is a tad too long for 28 MHz. You might need to trim a few inches from each whip to get the resonance up into the band where you want it. For exa
I will install my first beverage antenna soon. The ground has frozen, the snow has fallen, and the pond is growing thicker with ice each day. It's antenna building time! :-) I read many articles rega
Dave, The roof as you describe it should be pretty transparent to RF, unless the insulation has a metalized skin on one side or both. Have you tested the vswr with your transmitter and a swr meter? W
Gary, I have been contemplating the Opti 40/20 meter antenna for next spring. When your 3 elements are operating properly on 40m, what does your vswr curve look like? I see it is at 80 foot on your t
Ed, I concur... my wife had never seen the Mosley PRO-67b anywhere other than 90 feet in the air... and later in a crumpled heap after the tornado took my tower down... So when I bought a HyGain TH-1

Absolutely true Hank... and the more loss in the coax, the "better" (wider) the bandwidth will look when plotting the VSWR curve. 73 de Bob - KØRC in MN Not strictly true. Because of coax line
That was true in the old TIA-222-F specification. With the more robust girth of current engineers, 5 foot 6 inch spacing has been specified in TIA-222-G. 73 de Bob - KØRC in MN --Original Mess
Bill, I'm sending this at the risk of being repetitive and redundant to what Jim has already posted, earlier. :-) Your county will want to see an approximate scaled drawing of "things" like your hous
Pulled quote from below: "... most of the officials i worked with in FL and here in KH6 seem to think that towers fall over at the base sideways." Well I'd better delete these photos from my website

TowerTalkers, I don't have an answer for Wendell's inquiry. But... While cleaning out my shed for a garage sale, I found a 1971 Tri-EX tower brochure. I have seen requests on TowerTalk for informatio
I think ALL of the energy radiates, less the coax and tuner IR losses. If the RF doesn't radiate, tell me where the energy goes. 73 de Bob - KØRC in MN --Original thread-- Message: 7 Date: Wed
Roger, Take a look at this website to get a scope of work on a 90 foot self supporting tower project: http://www.kc0ll.net then select "My Home Tower" 73 de Bob - KØRC in MN --Original message
You guys discussion prompted me to look into the "counterpoise" for horizontal wire antennas. I found a brief article here, including some graphs. http://www.arising.com.au/people/Holland/Ralph/count
Using a Bird meter and comparing power levels at both ends is one method to determine coaxial cable losses. But this is impractical in many circumstances. Here's a link to an overview of how coaxial

I operated CW Sweepstakes from North Dakota last weekend. There was plenty of time (10 hours) to look at the flat, fertile, harvested landscape. I discovered the North Dakota pioneers DID have a sens
