[TVARC] SWR Problems

[richardmenninger at yahoo.com]

Hey all- KK4TG here and could use some advice or instruction or something. Have a Greyline 20’ flagpole antenna. Its ladder line is attached to a Palomar 1:1 Balun – line isolator which goes to an LDG RT100 auto antenna tuner. There is then 85’ of RG8u coax to the LDG RC100 controller to the ICOM 7300 transceiver.
Problem: Really good SWR on 20 meters through 6 meters. Terrible SWR on 160, 80 and 40 meters. I have double and triple checked all connections and can’t figure out why I can’t get an adequate SWR on at least some frequency on those bands. Any ideas or recommendations (other than trash the Greyline) would be welcomed. Thanks in advance! 73s -richard
