Bob, and the gang,
I added a random length of LMR400 coax between the output of the coupler and
the 1:1 balun.
I’am guessing I’m tuning the coax and not so much coupling energy into the
doublet. But now, the palstar and the Ten Tec 238 can find a tuning solution at
1.8000 mhz. Without the extra length coax length, neither one would. I have not
tried other frequencies yet on either coupler.
Remember, I changed the length of the coax from the back of the tuner to the 1:
1 balun. NOT the length of the 600 ohm feed line
