I'm using two Polyphaser rotor cable boxes with my 3 el. That leaves 4
extra terminals. I priced a 12 terminal Polyphaser box and the price was
more than I wanted to spend. ($300 +) Less expensive for two of the more
common boxes. Can't say how it works because I've not experienced many
thunderstorms since installing them. But the Steppir still is FB.
