The 8cm difference in the loop circumference comes from vortex, i posted links to mk1 & mk2 specs a couple of posts back,
im sure wire diameter does matter in real life & models Eddie, especially with close spaced conductors forming transmission-lines,
it is a pita that they cripple the free & inexpensive versions of eznec with segment limits,
what are you looking at starting @7 minutes that convinces you the mk2 won't do what is claimed ?,
i see a chinajunk s-meter registering local noise, that's normal for chinajunk,
am i missing something ?
The guy Dave is talking to is 25 miles east of me atcf, known him for many years, when he pumps up he's like a local,
he is about 7.5 miles atcf from Dave & using a coily excaliber .64 on a crank up tower.
i don't like how the Q82 mk2 handles in the wind either Eddie, its just a breeze & look at the radials flopping around, should have put the spreader in the right place,
They over engineer in the wrong places, use stauff clamps in stupid places where they are either not required or are a potential disaster,
an ass backwards engineering fugly fat sister version of my favorite antenna.
