NOTE this is not a suggestion that protection is not needed as many can
attest.
Although I ground the coax at the top and bottom of the tower, I have
never used any form of lightning protection on the rotator cable, or
control box.
I've mentioned before that the tower was taking at least three
strikes(visually verified by neighbors). Weather proofing and plating
was blown off a number of connectors, but no problems for the rotator
which was 10-15' down, inside the tower.
Rotator cable and coax ran together for about 175 feet.

At the risk of starting yet another discussion of lightning protection in
general I do have the following specific question.
In addition to an overall sound design for grounding, etc. is there a
significant advantage to having rotor control line surge suppressors at the
top of the tower? I have read that its a good idea to ground the mast to
the tower to bypass the rotor and I was already planning to have
suppressors on the control lines at the bottom of the tower and at the
entry to the radio room. The intent would be to have better protection for
the rotor itself especially its apparently sensitive reed switch.
Thanks.
