Hi Mark,
What software are you using for modeling? NEC engines do not like close wires
(perhaps NEC4 has dealt with this).
EZNEC or AO should handle the problem better.

It was MMANA "freeware" which uses the mininec engine. I finally got
it to work.
I wanted to try some other programs also. The first version I made
placed the wires at only .3m apart. "40m antenna" When I tried .5m, it
clicked in and started showing believable results. Around 300 ohms,
plus or minus depending if high or low from the design point. When I
tuned that particular antenna so I had nearly no reactance, I got
284.617-j0.444 . Thats probably fairly close. MK
