    If your rotor plate doesn't have the over-sized hole that accomodates the 
terminal strip, then you need to either enlarge the hole so that it does (and 
the wires don't touch/short out on the plate) or raise the bottom of the 
rotator up. Hy-Gain used to make a plate just for that purpose but you can 
use bushings, big nuts, washers, etc. to do the same thing. Current Rohn 
plates have the enlarged hole already. 

    I don't know personally of any 'ice under the rotator' problems but maybe 
someone else has. The potential problem might be more electrical than
