to any problem. Only caveat is the use of 115VAC coils, but
not a big deal. All the coax antenna relays etc. of the '50's
were also using 115VAC, E.F.Johnson used them in the KW
Matchbox'x for example. I paid $65 each for the relays, and
was thrilled when I saw the quality of construction!!
A means of not having to run the 115 Vac up the tower, would be to put a
115/6.3 v ac fillament transformer (as in Radio shack, ugh!) back to back so
that only 6.3 v ac is running up the tower. The transformer at the antenna
would switch the voltage from 6.3 vac back to 115 v to operate the relay.
