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
Be very suspicious of any e-mail received under the name "Nat Heatwole" for the next few days and don't open ANY of the attachments to them. These messages DID NOT originate from me and are most like
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
Looking over all of the preliminary score reports posted on 3830 I have found the following numbers to be true on 40m: Station: QSO's: Mults: -- K3LR 1595 119 W3LPL 1668 123 Using these numbers W3LPL
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
Fellow TT's: I will be taking a vacation to ID/MT/WY this summer and would love to take the rig along and hand out those rare states to some folks on HF. Most of the trip will be in an RV so I have r
Hello again fellow TT's, I once again seek your advice and wisdom. I am going to be erecting some ground-mounted vertical antennas for use on HF in the near future that would be fairly accessible to
My last post regarding a good portable DXPedition HF vertical antenna netted many suggesting the use of the Cushcraft R5 10m-20m all band vertical. Unfortunately, few were able to give me any die har
Hello. I'm wondering if anyone knows of someone who makes 40m, 80m, and/or 160m monoband vertical antennas? I am aware of GAP, Force 12, and Butternut, however all of their verticals appear to be mul
I've been thinking about getting an Auto-Tuner to solve some of my small (2:1 max) SWR problems and to keep my Alpha 78 amp as happy as possible. I chose an auto-tuner over a roller-inductor one sinc
