I got tired of losing terminating resistors and the matching transformers at
the feed, so I place low voltage gas discharge tube between the Beverage wire
and the ground rod, at each end of the antenna.
The gas discharge tube (GDT) will conduct at about 70 volts. When I bought
them years ago, they were about $1 each, for qty of 100. I also put them
across the input of my Beverage receive bandpass filters.
Haven’t lost anything to lightning strikes since I started using them.
