David, My company has started a division that will sell aluminum tubing. Prices of commerical antennas are out of sight especially for someone who is going to have a big station. All my antennas are

My opinion is that solid rock is a good thing and you will have no problems at all. Go with your gut. I can tell you are more nearly to err on the side of safety than 75 percent of amateurs. I assume

Anyone have a program that will correctly model a T shaped element that I want to work properly as a reflector behind my shunt fed tower on 160m? NEC 2 apparently does not handle it properly. If you

Barry, Two DPDT relays for each antenna - one for each rig. Activating a relay by Rig A with one set of contacts disables the other rig from being able to activate the same relay for the same antenna

Just my opinion.... 1.5 inch schedule 40 may be fine if you have some big tribander or 35 foot monobnder and it is mounted right above the top bearing. If you are stacking antennas on the mast, forge

David, HFTA will give some false information with close spacing for stacked antennas. I don't think you would want to stack them that close - less than a half wavelength. Not that you can do it but i

Peter, I would expect that if you have three 20M Yagis stacked for 20M that they are spaced something like a wavelength apart and the difference is in the angle that is covered by that high one which

Dick, I assume you will have a separate coax for each antenna. If so, you can use a simple series matching transformer at both ends. Assuming .66 velocity factor it would be about 90 inches of 75 ohm
