Hi, I'm new here, I caught the low band DX bug a few months ago - specifically 80 and 40m. I would post this idea/question to the top band reflector, but its stated they're 160m only, and this is not

David, Yardley Beers, W0JF wrote an article in the August 1987 issue of Ham Radio about a "new approach to designing trap antennas". It dealt with the design frequency of the traps being about midwa

Gents, I don't like nit-pickers so I hope I don't sound like one. It's called an Extended Double Zepp. And it's a very versatile antenna.End-fed 1/2 wave = Zepp Center-fed full wave = Double ZeppCent

Aage,The link doesn't work. Joe, K8MP To all! STUCK with that single radiation diagram? Why do you keep putting up 1 and 1 antenna? Why not making the Extended Double Zepp into another 2 to 128

Yikes! I've been spelling it wrong all this time? But Dr. Internet says both are acceptable, although I question his dates. It said Collinear was first used in 1863. Since it's a geometric term, that

I also agree. My DXing antennas for the lower 3 bands are vertically polarized. agree 1000%, re paragraph 1... 73, w5xz, dan Its hard to beat horizontal antennas on 20m and up due to the ground refle

Hello, this is my first post on this list. The folks on TowerTalk suggested I ask my modeling questions here. I'm using xnec2c on a Ubuntu Linux desktop to perform the modeling. Is anyone here also u

Hi Kevin, If you're just wanting to build 40 and 20 meter dipoles fed with one hunk of coax, just cut the dipoles, (468÷Freq in Mhz), tie them both to your center insulator, and attach the coax. You
