Tony, I know this has been said before but be sure you get 2" tubing not 2" pipe. Tubing is measured in outside diameter and pipe is in inside diameter. Also, be sure it is 6061-T6 alloy. Some other

I would say that it depends on how much wind load you will have attached to the rotor mast or how long your antenna boom is. If you have one antenna with a boom of 30' or less you would likely never

Sorry Jim but who ever told you this is full of it. 6061-T6 is a alloy that is designed to be bent a long way and not take a set. It will not crack or orange peel. Dave - K4SSU ______________________

Hey Gerry, Replacing your KT34a with a 2 el Steppir or a Tennadyne T6 would be a noticeable loss in performance on 10, 15 & 20 meters, however, you would add several bands that the KT34 can't cover.
