[Towertalk] hygain 205ca

[Major Ron]

Just checked all my notes regarding my now deceased 205. When set to low
phone, the resonance came in at 14.137MHz (according to my MFJ-259B). I
adjusted the antenna by setting it atop an 8-ft fiberglass step ladder
(reflector end down) with the antenna pointed stright up. The match was
adjusted with the 259B. When run up the tower, it played very well. Same
with the 105 & 155.

I would check your joints to be sure everything is clean and tight.
