[TowerTalk] 40 Meter Vertical

[n8de at thepoint.net]

Paul,
Many years ago, Dentron sold a 40m vertical just as you describe.
I have 5 of them .. three are in place, and the other two are under 8"  
of snow.
We have up to 18" more forcast for today and tomorrow, so will have to  
wait until it all melts or blows away to dig out the other two and  
measure the diameters/lengths.
When I can, you'll get the info.
