I've started construction of a 150 ft Rohn 45 rotating tower using K0XG 
base and four rings, top ring at 140 ft. Just above the top ring will be 
a 3L40 and possibly a small 20 above that, like 3L.

I'd be very interested in any experience or anecdotes on projects like 
this using R45. That tower was selected because I already own it. My 
area has the potential for icing. The ice I've seen is very light, 
nothing like back east or in EU. But I suppose its possible. Not too 
windy, the strongest seem to peak out around 70mph and that's rare.

One issue I see is, there are no torque bars on the tower. All its 
torque is transmitted to the rotator on the ground. K0XG's rings do have 
torque bars but that doesn't help the tower.

The general plot is to add antennas down the tower above the guy rings. 
Second 3L20, a shorty 40 Hygain, 10 and 15M.
