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.
