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 sign

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 th

Oops...That should have been three strikes per summer for the first 6 years it was up although the 6th year only two were verified with no damage. Computer Cat 5 network was something else, but in ov

Unless you enjoy repairing rotators, I would. I have either MOVs or GDTs on all of my motors and indicating sensors. I have not made any additional effort to ground the mast, it seems like the bearin

If the ball bearings in the rotator and "thrust" bearing are operating as intended then an oil film is insulating the races from each other and from the balls. Every rotator I've disassembled has no

How about some electrically conductive grease on those bearings?Are there conductive greases that meet the other requirements for rotor bearings? -Mike From: Grant Saviers <grants2@pacbell.net> To: j

MOVs provide overvoltage protection but have a downside as they degrade with every snubbing shunt and eventually fail. On an AC power strip, a failed to short MOV burned up a nearby ham's shack here
