[TowerTalk] 160m. full-wave horizontal loop

[Pete Smith]

I'm doing some modeling for a friend.  The antenna in question is a square,
full-wave 160m horizontal loop 32 feet above ground, fed 20' from one
corner.  The feedpoint impedance makes a certain amount of sense -- quite
low --  but the gain numbers seem very optimistic to me.  It's showing >10
dBi straight up, and >4 dBi at 35 degrees elevation. 

Modeling with EZNEC 1.0, using high-accuracy ground, and a current source.
Can anyone see the clanger?  Or is it maybe for real?  Looks like a heck of
an NVIS antenna!
