[CVRC] Lightening arrestors on 2m white sticks??

Jim,

I have all my antennas going through an MFJ-270 surge protector. It
claims to be able to handle "up to 5000 amps" of surge current. I
haven't tested that claim.

All protectors are at a single point ground system outside the shack. I
also use an antenna switch for the HF antennas that grounds the antenna
when they are not selected. This should prevent any static build-up on
the antennas.

And that's about all I know about that.

Dale
