You can, if you want, view the dipol as two pieces, each with one pole at the feeder and the other pole at ground. If the the two part are equal, as we intend to have them, the two "hot" poles, will
I think the idea is that you calibrate the true north against the READING on the controller. I believe that declination is rather constant at least in a short time frame, all you have to do is to dir

I believe there some "reasonable ..." in how much the "authorities" can charge. High fees can be construed a a way to stop us from pursuing our legal rights. Give ARRL a call and inquire about help.
Why wouldn't 60/40 Rosin Core Solder work outside? That's news to me and I have used it forever on any electrical connection inside or outside without any problems. What did I miss? Mike Baker K7DD K

This has been discussed many times. My suggestion: Put a copper or aluminum plate next to your ground rod. Drill holes in the plate and place female-to-female coax feed-through in these holes. Let EV

The "modern, power-saving" wall-warts contain a small, switching (and noisy) power supply. The "old" once only contain a (high loss) transformer, diodes and (sometimes) a capacitor. By-the-way, those
Now I wonder; if the wind blow your tower over AND the tower is securely fastened to your house, what about the house? I have seen these installations where rather substantial towers are supported by
In my case, the strongest argument was that the neighbor didn't want her horizon to be broken by technology. An other "interesting" comment was that there were no study presented how the RF radiation
I just wonder if I can get some input. I was thinking putting a "stick (conducting)" on top of my tower well above any other installation. Connect the "stick" to a heavy wire that is well grounded in
Maximo, You contact a local tower manufacturer or e.g Universal Tower and buy ready made sections. First: You don't use pipes, like water-, but tubes for a tower. Second: I don't recommend you dimens
I wouldn't trust it as guy wires. The wire is intended to conduct current. If you open up a little of the cable and "mess around" with the wires you find them very brittle. If they left some 5/16 gal
Best (in phase) scenario you will get better signal. The other question is whether you will exceed the power limit. You could, theoretically use two, maximum legal power and end up with four times re
Fellow Hams, I believe I have one way of measuring the stress in the guy wires. I would like to have some comments whether I'm right or not. Consider the guy wire as a string in a guitar. The vibrati
After some (a lot) difficulties my tower is finally in position. It is not put up in a "normal" way but rather the way I found practical and applicable. You find the pictures at _http://www.facebook.
The idea is that I can inspect the ground connection. I also didn't want to have things interfere with my lawn mower. I kept the wires as close to the rod as possible, thereby minimizing the inductan

Yes, you should be able to build a multiband antenna that way. I did something similar for a mag-mount for 144, 220, 440. I used one pin/wire that tuned 144/440 MHz ( I cut it for best SWR for 440) a
