Perhaps this is a little off topic, but I am sure that there are some readers of TowerTalk who are former members of the University of Illinois Radio Club or perhaps you know someone who is. Jay was

There are LOTS of different options for guyed towers, but you are correct except for I think you meant to say "unguyed" the first time! For guyed towers you have: * pier pin base (what I use) * stand
Hi gang, I am not able to go to Dayton this year and the person who was going to use my room at the Crowne Plaza just backed out. So I have a reservation there. First one who responds to me gets it.
Thanks to Steve for suggesting using a clove hitch for attaching a pulley to a mast. I just took down my old TA-33 (putting up a Skyhawk instead) and the clove hitch around the mast worked great! It
Since I am replacing antennas, I figured I would take my rotor down and service it since in the 6.5 years I've had it I've never done it and who knows when it was serviced previously! It's a Ham-M. I
Very simply done. Go to your local home improvement store and purchase a tube of Noalox. It's designed specifically for this type application. It prevents the metal migration and corrosion problems.
Mike, I would go with the F-12 C4SXL. It has 2 elements on 40 meters and covers 20, 15 and 10 as well. It's definitely a very good antenna. Someone else mentioned the XR-6. That's even better, but I
I'd agree. It's quite apparent that this guy did not do a proper engineering analysis of the requirements and loading forces on his tower. He's still likely to have problems in strong winds with his
And knowing Greg, personally, I can say that he lives on a ridge that gets hit by extremely high winds! How many rotors have you broken due to the winds, Greg! :-) installation. 73, Jon NA9D -- Jon O
Beating up on people doesn't work unless they willfully do the same thing after being instructed properly. However, treating them as though they are doing their best all the time is a recipe for fail
AFAIK, you can loop the guy wire around each vertical tower member and apply the appropriate guy grips or cable clamps. It's better to have the guy attach assembly as it clamps AROUND the tower and d
Howdy all, I've just finished putting up my VHF/UHF/Satellite antenna array and have a question about the rotor I am using. My azimuth rotor is an AR-22. I purchased it at a hamfest for $20 and it ce
No, I've not done that. I have no instruction manual. How do you do that? Also, the rotor seems to turn faster in one direction (clockwise) than in the other (CCW). The "clicks" come a lot slower. Is
Thanks to all who replied on my questions on the AR-22. I have decided that while it may be a decent rotor for a small HF beam, it just is not going to be satisfactory for my uses in trying to track
While I am a major bowline fan, I don't know if you'd want to do this. Knots do reduce the strength in a line. So your knot would reduce the strength of the Phillystran. I forget by how much but I th
Hi Bill, The first question is what would you like to use the tower for? And second is how much are you able to afford? The second is the easiest to answer quickly. If you get a "free" tower, plan on
No, the original poster is correct. This isn't the forum for discussing RFI, but the facts are that RFI is NOT our problem if we have a well designed and engineered station. If a neighbor is unwillin
A couple of years ago, I was talking with Earl (applications engineer) at Amidon about this very subject. I had a computer monitor cord that I wanted to put a ferrite on but the connector was too lar
I discovered this myself. Here's what I learned. The rotor plate is specifically designed to be installed in the bottom part of a Rohn top section. The bottom part of the top section lacks a couple o
