Dear Gunner,

It's expensive, it's a "loop," but it might be just what you're looking
for! Check out the AOR WL500 Window Loop Antenna.

I own one. I use it with my Grundig Satellit 800. It's relatively
non-directional above 6 MHz. I like it very much. I believe AES and
Grove also sell this antenna.

Hope that's at least of some interest to you.

Best,

Joe
