I just bought an LM354HD tower that is still standing. Weight is close to 1000Lb and it stands about 20feet nested. Any ideas how to get it down safely without a crane? It does not have the tilt over
I have an old Mosley TA33 and yes they did recommend grounding one side of the driven element to the boom with a strap. If I remember right they also recommended a choke made of several (8 or 10) tur
I have lots of old copper clad telephone wire that I want to use for radials and antenna wire. This is the stuff that is bare and went from pole to pole for old telephone lines. It is not the insulat
Well, the copper thickness does make a difference at low HF frequencies as RF penetrates deeper than it does at higher frequencies and can get down to the steel and losses go up. A very thin copper c
Jim, You only think that there is no ground between your house and shack/garage. That neutral wire is serving both as ground and neutral between the two buildings. What you are doing is no longer per
The whole purpose of the 4 wire system is to keep neutral current off of the ground wire. With a 3 wire system, if the neutral/ground should open there could be 120 volts on cabinets that are connec
Maybe where you live the local board had not yet adopted the newer NEC code? Current NEC code does not allow for only 3 wire feeds from one building to another. They require 4 wires. Neutral and gro
Jim, Very important as to not mislead someone on this. If you have only a 3 wire feed system from your house to garage then you have to have that feed neutral wire bonded to the panel at both the ho
Ranges and dryers of yesteryear had only 3 wires, 2 hot and neutral/ground. They had to be on a dedicated circuit so as to not energize some other appliance on the same feed if there was an open neut
Yes Jim I believe that you said that in your first post. But in subsequent post you seemed to argue that there was no ground running between buildings and made it sound as though the neutral was not
Hi Roger, Yes I agree it would be dangerous. But probably no more so with either feed system with proper neutral bonding. 73 Gary _______________________________________________ _____________________
I don't know if you are including me as one who is "railing against you" but this is exactly what I have said from the start. shack/garage. is specifically listed as acceptable in the last code I bou
I am helping a friend with an 80 meter 4 square vertical. Can someone tell me how to calculate the difference in length when 4" aluminum pipe is used for the elements verses wire elements? Thanks Gar
Thanks for the info John. My computer doesn't want to open the wk1 files of the program. Any suggestions? Thanks Gary K4FMX _______________________________________________ ___________________________
I agree. The capacitor is the first thing that I would try. Just clip another one in and see what it does. 73 Gary K4FMX _______________________________________________ ______________________________
I had a TA33 up several years ago. With that strap grounding half of the driven element it had a nice broad SWR on each band but it had two resonant points! One was near where you would expect and th
Hi Allen, You do not want concrete in contact with aluminum! It will eat up the aluminum. Even aluminum windows come with a warning to not let the brick mortar come in contact with the aluminum frame
You should have taken the physics course too. :>) The old "bumble bee shouldn't be able to fly" is an old wives tale that has been around for ages. 73 Gary K4FMX _____________________________________
Hi Patrick, No I don't think that I misunderstood your meaning but maybe you misunderstood mine. :>) The old rumor about aerodynamic engineers claiming that the bumble bee shouldn't be able to fly, i
Part of the reason for the arrestor on the coax line is because the center conductor is going to have a voltage different from the shield. The tower and all of the lines coming down the tower share a
