My TH-3 tri-bander crapped out during the Sprint this last
weekend. (My matchbox allowed me to keep going, but my antenna
gain was clearly kapoot).
The symptom: SWR is 3:1 on all freqs on all three bands, i.e. no
dip in the SWR curve anywhere. Anyone had experience with this?
I'm assuming a trap has shorted (opened?).
I've had the antenna about 7 years. Yes, it's been raining a lot
here in S. Calif, but the antenna crapped out after a week of warm
And how does one troubleshoot such a thing?
