Re: NEC-LIST: bogus currents

 
Mr Bingeman,

One possible explanation may be circulating currents for "small loops"
as discussed in Para 2.2 of the NEC-4 manual.

Subject: NEC-LIST: bogus currents

When I model a Trylon STG 50 foot tall tower over perfect ground, NEC2
and NEC4D both find outrageously high currents in the tower rungs near
the bottom and top of the tower at 1000 kHz. No NEC geometry rules are
violated. The tower face is 18 inches wide, and each 10 foot section
has 8 "blocks." Each 15 inch tall block has 3 diagonals, 3 horz members
and 3 legs. One current segment per.

I can send you a NEC or EZ file if you wish.
