[TowerTalk] 40 Meter Vertical

[Jack/W6NF]

I've been using the 4-foot aluminum cammo support tubes (1-3/4 inch OD 
and fairly thick wall) for some years now and they work fine for 
1/4-wave 40-meter verticals. I have mine guyed only at the 32-foot level 
with Dacron line. I am also using the cammo support tubes on a 48-foot 
top-loaded 80-meter vertical guyed at two levels. At 48-feet, however, 
the tubes are pretty flexible and not easy to erect without bowing 
unless you use a gin pole. Once up and properly guyed they are fine in 
any wind up to at least 80 miles-per-hour...based on my personal 
experience here in northern Nevada.
