Topband: Coupling between bev and other antennas

[john devoldere, ON4UN]

The coupling was on 160. The elevated radials are for the 80m antenna. On 80
the Beverages did NOT have the same problem (at least MUCH less). Also, the
coupling was clearly demonstrtaed by modeling the exact situation using
eznec.
