Bill, et. al., I agree that the Ham series rotors will have problems with big antennas, however, if you are on a budget and you know about the modes of failure, you can make them work. Two of the rul

Hi All, I am trying to move the AS455G I have up a couple of feet in my Rohn 45 tower to give me just that much more separation between my KT-34XA and a 4 element 17 meter monobander I want to mount
The crowbar worked. They make these so close a fit, they are just plain hard to put in or remove. 73, I am trying to move the AS455G I have up a couple of feet in my Rohn 45 tower to give me just tha
