<< ...I beg to differ! People have built aircraft for decades using much thinner tubing thicknesses than Rohn 25 or 45 have. Naturally, thin-walled tubing is a bit more challenging to weld, but the t
Hello All, I am planning an antenna for our club to use this summer for a special event station adjacent to a lighthouse on a sandy island in Chesapeake Bay. I acquired two very nice, 33' telecoping
I went through quite a bit of debate trying to decide which type of antenna would crown my tower. I can't directly address the original question about ice survivability with my own experience. Others
Just to show that I am not biased against quads - quite the contrary. I like to participate in RF foxhunts with the local club on VHF frequencies. All the leading hunters are convinced that the quads
Greetings gang! Welcome back, TowerTalk! A big thank you to George, K0FF, for the tip to use nylon grommet strips for winding inductor coils. These things are great! After finally obtaining some in t
Greetings Gang; I have been following the discussion of counterpoise systems for 0.25 vertical radiators with great interest. I especially liked the suggestion to use forked radials. It occurred to m
I seem to remember reading a post way back in the archives about a way to homebrew your own detector for charge fields that were strong enough to become dangerous. It centered around using a sensing
I have been working on inspection lists for new and used tower sections. With the recent thread, this seems like a good time to ask for further comment. here's what I have so far: INSPECTING NEW TOWE
Hi David; I'll try to address each or your questions below... << If the end of a top section is bent a little where many of us have allowed one leg to stay in the tube below as we tilt the section du
Jim Clark asked: << snip.. If I have a 2nd floor shack, should I use a Polyphaser entrance panel, or ground the antenna at ground level with a suppressor, and run coax up into the shack? Hate to dril
Hello Pete, I have done something similar for a friend's tower. I think Steve is right on about slacking up all three existing top guys. The tower will not go far enough to do any harm and the slack

Hi Bob, what do you think of installing a surge arrestor at the 120VAC wall outlet that supplies the battery charger, then winding the charger's power cord into a choke coil, making it a high inducta

Hello TowerTalkians; I would like to develop an inspection checklist and schedule for my guyed, R25 tower. Do any of you have a list, already made-up, that you can share? I appreciate all of your ide
Greetings from Gloucester, VA I would like to compile a reference of how the different models of rotors fit into Rohn 25 tower sections. Please email me direct and tell me the make and model of your
Hi Don, Yes, HF J-poles really work! I think of it as an end-fed vertical dipole. My first 10m & 20m antennas here, before I put up my tower, were homebrew wire j-poles pulled up into trees. They wer
Hello Tom et all; I use a trick at home that might help out here. It is important to neutralize the acid after using it as a soldering flux and rinse away the residue with several rinses of plain wat

Hello Jack, As reported in prior posts, having some weight on the rotator is a good thing, as they are designed for a vertical load, which helps keep their bearings seated and wearing evenly. This al
