Its hard to have a tall tower on a 1/2 acre lot that is guyed even if you use less than 80% for guys. This makes these self supporting towers very attractive especially to XYL's and eliminates the pr

There was a great article (before most modeling programs) by W9LT (now also WA7LT) on testing parasitic elements as refectors and directors. Although empirical, the summary shows that you must be car

Rich, W6KPC has been selling his "Clement" Tower on ka9FOX and other classified pages. He wants $5k for his 140 tower (better than Rohn 55) and has all the material you need to guy and rotate the tow

I remember that Jim Reid, KH7M tried to reconstruct the multiple V beams that W6KG described in a mid 1950's CQ when Loyd was in DL4 (Germany). Jim had logistics problems with keeping it in the air a

The 40-2CD is a great antenna on 17. The only ones who beat me are the gang with multi element mono-banders. The SWR is 1.9 to 1 so some transceivers will require the use of a tuner. Bill K1MM alerte

I agree with Steve K7LXC that the rust is probably not a problem. Prelube 6 will do the job. Check the pulleys on each section. There are probably enough people here on towertalk to scare up a few US

I have two e-mails (from 2 different hams) and a phone call from a local that all tell me no manual or instructions are sent with any tower these days. 5 Years ago they continued to provide a manual

CORRECTION All but one who e-mailed me or called me said they did get base instructions but nothing on the tower as to a manual. This makes the towers useful but lacking in documentation. Where is Lo

I run my coax out side the crank up and the rotor cable inside. I have an old Tristao 71 footer which is about the same as the TX series US Tower. I have three antennas with coax to a remote switch t

I saw another post asking if anyone outside of US Tower or Tri-Ex made crank up towers. The most recent company to pull out of towers was Telex Hy-Gain although there is some talk about bring back th

I don't see any reason why the old telephone pole mount that was in a 1956 or 57 QST and in the ARRL Antenna book for years would not work for a tree mount. You would need to clear the branches off s

US Tower is a small company with plenty of business. Several years ago they stated plainly that you should deal with their re-sellers rather than calling them. Rohn is exactly the same way. I did get

I have the same problem that Dave K1HT is experiencing. Right now my rotor is stuck on 20 degrees (I was trying to hear 9N7AS on 17). Rocking it back and forth doesn't work but it will turn after a d

The T2X is a good rotor but requires almost perfect alignment to turn properly without sticking. I have mine mounted in a Tristao 71 foot crank up (now known as the TX-471 from US Tower. Some of the
