I did model this antenna with EZNEC but I forgot to take

that screwed up the resulting antenna. Maybe? Would an
insulating jacket reduce the VF of the wire?


Yes, most of us have been bitten by that bug in our
thinking. Exactly the same thing happened to me with
"My Favorite Loop Antenna" on my web page. If I remember
correctly, the insulated effect is around 3% on VF.

Thanks for the info, Cecil - I just got back in the shack from
trimming all 3 elements. The SWR is now pretty close to what
EZNEC predicted. I can't tell if I've got any pattern on SSB
because 6 is wide open and full of contesters. There is a beacon
80 miles away that I'm hearing and I'll try to see what kind of
pattern I have receiving that.
