[TowerTalk] Vertical with no radial wires

[Bob Nielsen]

The Hy-Gain AV640, Cushcraft R8 (etc) and some of the Gap verticals  
have minimal counterpoises and if you elevate the base a bit above  
the roof, there shouldn't be any problems.  I have used a AV640 for  
the past 7 years and am pleased with the results.  It is mounted on a  
15 foot length of pipe with the base about 2 feet above the edge of  
my roof.  It's not rated for 80, but I have made contacts over 2000  
miles on both 80 and 160 running 100 watts under the right conditions.
