Topband: low inv-vee

[Carl]

Some of my best, and easiest, 160 DX has been to the Antarctic area and 
surrounding islands with a coax fed 160 inverted V with the apex at 60' and 
the ends at 3'.

Apparently NVIS into a duct with little attenuation since it rarely took 
more than a coupleof calls. Im also on a hill in the country here in NH.

Carl.
