Mike, that EZ file will not import into my 4NEC2, the free version. It may be too involved for my cheapo version (5.8.16)? I've imported other EZ files, but not this one. Thanks for trying, unless you have another suggestion. Actually, I'd like to compare the square to my fairly high dipole (80 & 40) with real ground. If it is good enough, I might want to try a 160 version where I have no antenna. I've got the space and probably the height.
