Bob, John, and the gang,
Why the palstar can’t match at 1.825 and the Ten Tec 253 can, yet the palstar can easily match the doublet at 10.120 and the 253 can’t
still remains a mystery to me.
I did notice that when I added the extra feed line and extended the antenna length, the palstar previous setting are now way different. I don’t know how the roller inductor is calibrated i.e., does 200 mean more L or 200 Less ? I don’t know.
Without the wire extensions, 40 and 30 meters came in with a L of 79 to 83, but now, they are 170 to 190.
I have a half-dozen antenna couplers, all from Ten Tec and will swap in a few to see what happens.
The quest continues….

> I agree with Bob. But, having no technical background I tend to do things the 'ham' way. I'd try a different 1:1 balun. I know they should be the same, but experience the problems you describe with a wound balun at times. The problems are not there with a sleeve balun. And, sometimes the sleeve had problems but the wound one doesn't. A choke balun is another thing to try.
