Ted- I have an 890AT, used with a 135 ft Dipole, fed with 450 ohm ladder
through a 4:1 balun,that tunes well on everything above 160 except 40.
I have a couple of questions.
1. how did you couple the Zepp ladder line to the 890?
2. did you increase the feeder length when you raised the Zepp?
what are the dimensions of the Zepp?
Thanks- Bill- W4BSG
