Maybe reflected power off of nearby objects is the cause of poor

Anyway, I am satisfied with the Arrow end fed antenna in the attic.
But, I am disappointed with my home made J-Poles. Maybe I will try a
little SO239 1/4 wave, just to see if there is any difference.


I'm wondering if you are using a common mode choke? Also what type of
mast are you using to support the antenna?

I have tried with and without a coax loop, 5 turns about 6 inches in
diameter. I couldn't see any difference. I use a 1/8 inch diameter
rope to hang the J-Pole from a joist in the basement or from a roof
rafter in the attic.
