[TowerTalk] More dipole support

[Grant Saviers]

I've found threaded aluminum conduit at the recycle yard for scrap 
prices.  I use it for a falling derrick 20' long in a 2 1/2" size and 
think it will handle modest load to 30' self supporting.  You can also 
strengthen a mast with spreaders and down guys that only go out 5' or so 
- see sailboat masts and power poles with this type of guying.
