What kind of resistors are you using?
They shouldn't do that if you use
After recent night time thunder storm activity, two Beverage antennas lost some
directivity. Termination resistors looked normal, but an ohmmeter checked
reviled they had each gone
hundreds of ohms higher. Replaced resistors and back to normal.

carbon, but need to find something
better like carbon film.

What kind of resistors
They were supposed to be non-inductive carbon, but need to find something
better like carbon film.
Any resistor except a big wire wound is non-inductive on a low frequency
like 160.
What you want is a composition type resistor, either metal or carbon, to
handle surges without changing

Thanks for all the termination resistor replies. Will look for Ohmite OX and OY
series resistors.
The resistors I had were supposed to be Carbon composition, but must not have
been. Will discard remaining ones.
Thanks again,

I have never lost one of those to a nearby strike.

Cut one open and look at it. You can tell right away what they are.
