Jan, Suggest you do not remove the old rusted cable until you are ready to replace it. It can be used to PULL or GUIDE your new cable through the tower sections, so that you get it routed the exact s
Dave, Near as I can tell, the 70 MPH number for UST is the only one that has the PE's name behind it, and thats for the antenna at one foot above the tower top, with the tower at full height. I suspe
Jim, I noticed the same thing on my UST HDX-555. The raising cable is all soiled up, while the tilt cable is clean - like new. Only thing I can think of is that I put that cable lube from Steve K7...
David, If you have Excel on your computer I will send you a spreadsheet that is already set up for the HDX-555. You simply need to input your antenna parameters (wind load & height above the tower) a

I've moved two crank ups (Tristao CZ-454FS ~ 400 lbs, and a UST HDX-555 ~870 lbs) from the front to the back yard by using ~ 4-5 inch heavy duty PVC pipe as rollers. The HDX is a bit more challanging
In my UST documentation, the only numbers that have a PE's signature next to them are the numbers given in the Engineering Specifications. For the HDX-555 it's: 23.2 sq ft (350 lb wind load) at 1 ft
While you are at it, you can also put a great circle map behind the pointer. I think I used "AZMap" which allowed me to center the map on my QTH and also color the oceans blue. A little bit of fidgit
See the article I wrote in QEX July/August 2001 re Tower Wind Loading. If you have a free standing tower and can verify from the engineering specs that the worst case moment is at the base, you shoul
I have been using the F12 WARC 2/2 for several years. Extremely simple to put together. (~50 ohm driving Z, so no matching section required -just connect with a balun). Works terrific. Have worked ju

Jerry, what you suggested below is pretty easy to do with a crank up tower (with some restrictions). I decided in 1968 to not be a climber and go with the crank up type of tower. What I'll describe i
Iv'e purchased Fultons from Northern Hydraulics - Home office in MN: 612 894 0326. They are nation wide ~ 36 stores. Frank W9JCC On Mon, 25 Mar 2002 07:40:08 -0700 "Richard Zalewski" <w7zr@citlink.ne
I have been using the Dow Key Series 71 (6 pos) and Series 72 (3 pos) since the mid 60's as remote switches (one or the other of them has been at the top of the tower since 1968), with no problems on
I saw this story on Milwaukee's local Channel 6. They gave the gentelman's age as 83, and that he had been a ham for 40 years. They also did make reference to "Amatuer Radio" and showed his shack. Hi
If you have or can get hold of Delorme Topo USA or similar software, you can get the latitude and longitude easily as well as your elevation. Zoom is from entire USA down to your local streets. Frank
Just thought I would share this free standing crank up tower experience with TT's. If anyone else has had a similar experience, or expertise to offer, I would like to hear from you. I have a UST HDX-
Tom, I built my TH6DXX in 1968 for LO Phone using the dimensions in the book (the ones you noted included) and the SWR curves matched the ones in the book within 10-20 Khz. Frank W9JCC On Fri, 23 Nov
They must have built them good in 1968. My Ham-M turned a TH6DXX from 1968 thru 1998. It was still working fine when I retired it. The pot was beginning to get scratchy and the terminal strip was cor
