I saw someplace on the internet that someone had modeling files for the Hy-Tower (18HT) by Hy-Gain (now MFJ), but that person told me that their computer crashed and they no longer have them. Perhaps

Hello Jim, No I never found the modeling file for the Hy-Tower. I guess it must be lost forever. I thought someone here might have downloaded it, but if so, they didn't answer. NOTE: To all the peopl

4. [TowerTalk] 160 M OCF antenna (score: 1)

Jon, Two things explain your problem - and they're both "to do" because of "wavelength". First your 160m OCF is very close to ground in terms of wavelenth. 1.8 MHz is 166.67 meters 2.0 MHz is 150 met

I've used a two horizontal beam (wire) for 40 meters headed NW - we chose the angle to put the European short-wave broadcast signals on the side of the antenna. The first idea was to target the place

6. [TowerTalk] Two Inverted "L"'s and one feedline. (score: 1)

If the total length of radiator on each band was a total of 1/4 wavelength, it would be just like a fan dipole. People feed these with one feed line easily and they can be configured to be very broad

Off Topic. Can anyone recommend a household light dimmer that has low R.F. noise? The one in my dining room makes a racket on 160 meters and AM bands. 73 David N1EA __________________________________

Steve K7LXC mentioned that he had done tests on the PRO series of Mosley antennas, I wonder what he found the figures to be - he reports negative numbers. On which bands? I operated a station where w

Search around for a FELCO cutter - made in Vero Beach, FL. They laugh at stainless steel - no kidding! No effort, just clean snip! I've cut Kevlar rope also with them. 73 DR David Ring, N1EA ________
