1. [TowerTalk] Trees Impeding HF Signals? (score: 1)
Author: heatwole@clark.net (Nat Heatwole)
Date: Wed, 11 Jul 2001 19:21:36 -0400
This is substantially more of an issue at VHF/UHF, but I'm wondering how much trees/shrubbery impede signals at HF? If your antenna has to "see through" a fair number of trees to get to EU (for examp

I'm wondering what the collective TowerTalk wisdom is on mounting towers in close proximity to buildings? Close enough so that it would be physically possible for the tower, if it were to fall, to fa

Does anyone know how to calculate the dB loss equivalents for given SWR values? Either a on-line chart of the equivalent loss for all SWR values or a formula where I could plug in various values and

Whoa. Thanks for all of the fast responses. The most popular suggestion appeared to be looking in the ARRL Handbook. I checked out the handbook and with some consideration I figured out the following

Hi all. I'm wondering if it would be possible to drive a Hy-Gain T2X (or similar) rotor with the control box from a TIC Ring Rotor? Obviously, if this was possible, some modification would be necessa

I've search the Internet as well as ON4UN's book very thoroughly, however I have not found a conclusive answer to the question of how many raised radials to use on a lowband vertical antenna. So, I t

Sorry for the mistake, I was thinking of KC1XX not K3LR when I wrote that K3LR was a little closer to EU. There really is not much difference in distance from EU between W3LPL and K3LR. Again sorry f
