What kind of antenna? 80 and 20 meter rotary beam? --- Balun will not stop
RF pickup if coax does not come away at right angles to antenna. And may
not stop pickup on rotor cable. Use beads over this cable at top and down
near control box (one or two 1" long beads over the whole cable). They will
improve the effect of the .01 caps. Use ferrites on the rotor 115v power
cord. You could have RF pickup by house power wiring that could channel it
to the rotor. -- Jack, K6NY
