My first loading coil was link coupled and I had same problem. I have
thought of adding
spark plug between antenna and ground, think I will do that.
Back before the turn of the century I worked for an electric motor
manufacturer. One of our
other divisions made submersible pump motors. the company had a patent on
a lightning arrestor.
It was a ball of brass or copper filled with argon gas with an electrode
inside. Very effective. I have
considered using a large neon lamp for the spark gap, but I haven't seen
any lately. I will probably
use auto spark plug.
Only other option is to move out of tornado alley!
thanks for responses.
Paul

Hi Paul, Lowfers,
I agree with Mike WE0H about a bleeder resistor or choke to
get rid of any charge that builds up on the antenna. My setup
has the xmitter link-coupled to the bottom end of the loading-
variometer coil, with no direct connection. Knock on wood,
I've had no troubles with blown finals. The antenna is D.C.
grounded via the load/vari, and in addition to that I've put a
spark plug connected between antenna and ground.
