Hi Lee
I think if you are not using a balun, the length of coax will make a big
difference in the SWR. You might try adding a chunk of coax and see if it
changes the antenna. I have a couple of antennas here that I use that
method to tune. They were alright at the base of the vertical, but in the
shack, the SWR was higher. Added about 10-15 feet of coax and brought all
back into spec. Yes, I know, that is not the way to do it. 73
