[TowerTalk] TowerTalk Digest, Vol 39, Issue 28

[Jerry Reed]

I have used 3 different Rohn HDBX towers over the years and have had 
good luck with them however I didn't ever use them with extra large 
antennas.  To use the bottom 3 sections, mount the rotor near ground 
level and run a 20 ft or longer section of tubing from the rotor to the 
elevation rotor and you should be good to go, no twist concerns and at 
24 feet the tower should be adequate for any thing that you can hang on 
it.  They are also reasonably priced and new components are still available.
