It occurred to me that my 45' tall tilt-up vertical made from 2" O.D. thin wall tubing may be germane to this discussion: http://www.dellroy.com/W4EF's-Ham-Radio-Page/Stew-Perry_El-Mirage/El-Mirage.h
Yes Dave, *I* was one of those idiots who attempted using an HDBX48 tower to hold up a KT34XA and a 14 element 2 meter beam atop that!! Unfortunately, I can no longer find any of the photos of that d
...one method to increase longevity of the HDBX48 tower is to mount the rotor on the tower base section using angle steel and a rotor mounting plate or direct ly on the concrete pad and run a 2" pipe
Dave, You have a very good suggestion that has not been brought up before. Mount the rotor lower in the tower or at the bottom to reduce the twisting action. Excellent. -- Doug Renwick VA5DX PO Box 5
