Greetings, I have had a few maintenance jobs on BX style towers and I alway end up with bruised feet after a climb. I wear a heavy boot with steel shanks in the soles but the problem is the bruising
One item not mentioned was whether or not the rf ground was disconnected. When I am disconnected from the antennas, rotators, and tower, I am also disconnected form the rf ground. My fear has always
Greetings, Let me chime in with my experiences. If you already have a tower up, retrofitting to a bottom rotor will be a major undertaking. Building up the tower and mast at the same time is far easi
Mike, I had a Triex LM470E tower with a raising fixture and I always encountered the same problem. My solution was to tie a rope near the top of the tower and have someone tugging on it as I let out
Greetings, A lot has been made of the pro and cons between N and UHF connectors. Are there any pros and cons to other types of connectors such as DIN and EIA flanges? Is it more pronounced at microwa
Hi All, Can anyone identify the manufacturer or model of this style tower in this eBay listing? The item number is 150112849868. Tnx, Jim W5QM _______________________________________________ ________
Jim, That's assuming the dish will be aimed at the horizon. What is the intended application, terrestrial or lunar? If for EME, I don't understand the height above ground. The advantage of EME beside
Greetings, I cannot attest to the modern cfl lifespan but I have a pair of Philips SL 18/27 still in use. I won these at a parade of homes 20 years ago. I would agree that the color has warmed over t
Greetings, Can anyone help identify this antenna? It is a ~108-1300 mHz log periodic with a boom length of 54", longest element of 55 3/4", shortest element of 3 3/16", the booms with the shorter ele
Hi all, Any recommendations for a welder in the Dallas/Fort Worth area to do some aluminum welding for an antenna and mast assembly? I have MIG capability but don't want to invest in more equipment,
Clint, Why settle for a loaded vertical if you are in the country? You are only talking another ~20' of height for a full sized 1/4 wave antenna. If you do proceed with this design, consider doubling
Bill, Unfortunately, we live in a litigious society where no one is responsible for their own actions, we are all victims. That said, I am running into the insurance/ bonding issue with greater frequ
Patrick, There is another issue you must contend with- drainage of water and condensate from the tower legs of any tubular tower. I am a tower monkey in the DFW area and I cannot begin to tell you ho
Greetings, Any idea on the manufacturer and model of the following described tower? Circa 35 yr.s old and almost identical dimensions and weight as Rohn 45G. Leg gage the same. The big difference

Doug, I think it was answered by the fact that the particular installation was for an antenna that was rarely rotated. I too have witnessed this on a number of installations where an antenna was stat
Dave, Before you go overboard with the aluminum, consider a (wire) cage vertical supported by the tree. Just run multiple wires up the trunk, bonding them at the base and at the top. As for an 1/8
For get the idea! The masts were designed to be used with only a couple sections joined together to support a tent or canopy, certainly not robust enough for 40', let alone 70'. They are too loose a
I have worked on Rohn 25 towers with ground mounted rotors. 2" aluminum conduit was used as a mast, threaded couplers were through bolted, and HDPE , UHMW, or Delrin was used as sleeve bearings every
