Re: Topband: Tower insulator thickness?

I tried an insulating sheet under a tower plate and regretted it. I had
problems with water in the dielectric area detuning the antenna, and it
eventually carbon tracked and failed.

I exclusively use power line insulators now. I use the type with a flange on
one end and a threaded stud on the other.
