Hi all, I am in the process of setting up an outdoor AM/shortwave antenna, I will be using an old TV tower and am wondering about installing some sort of lightning protection, I have a couple that are resistance type but I cannot measure any resistance with my meter, any Ideas on this, and also some suggestions on a type of antenna that would give good results.

A lightning arrester would have a very high resistance, most likely it is off the high end of your meter. It is not likely open.
They have to have high resistance else the surge current when the lighting hits would be extreme.

Best Regards,

Bill Grimm

Bill:
Some lightning arrestors have an inert gas (e. g. neon) that does absolutely nothing until its firing potential is reached and then becomes a short circuit to Voltages over, say, 60 Volts. That might be what you are testing. They work really well, grounding small charges that would never jump a spark gap.
