I place all rotor wires and other cable through a few 3" Ferrite rings
at the base of the tower with as many turns as I can squeeze on. Before
doing this I had a slight deflection in the rotor indicator at the shack
when I was on 160. Now I have none. The most sensitive item may be the
heavy bare wire indicator pot inside the rotor case. Yet I have never
lost one to burn out from RF.

Reading about 3-wire cages and the like, I feel a serious case of shunt
envy. Mine is a single wire about 18 inches from one corner of my Rohn
25, connected to the tower at about 50 feet. I used an omega match with
a couple of 3 KV transmitting variables, because my tower is quite tall
for 160 (97 feet with 3 yagis, 2 on top) and I could not find a 50-ohm
point.It was absurdly easy to adjust and seems to work quite well at 100
watts. I'm sure there are better solutions (including Herb's), but this
was really simple.
