Thanks to all for the responses.
I've had several types of Baluns here.
On a Hygain beam
A Hygain transformer type....was the best....blew up with hi-SWR
Ferrite bead W2DU..RF all over..... antenna pattern skewed....blew up
with hi-SWR
On the TA-33
The choke balun ....RF all over...antenna pattern skewed. ..actually
F/B and F/S disappointing..
The SWR has been climbing for months (all bands) The balun is suspect,
(I used foam dialectric cable and I think that the center conductor
might have migrated) but it could be the feedline or a trap.
I am changing the Rotor (to a Yaesu 800SDX) so as long as I'm up
there......
Will let all know the outcome...
Jim, WB2TPS
