masts

[Rich L. Boyd]

One source of masts used by some in Maryland is the local fence 
installation company (Long Fence Co.)

I go in and tell them "I want your strongest 3" pipe."  I haven't been 
knowledgeable enough to even know to ask "what schedule is it?" but I do 
know I have bought 21-24' lengths for about $50.  One has been up for 
eight years holding a 6-element Telrex 20 at 120' on the thrust bearing, 
with an 8-element Telrex 15 eight feet above it.  So, empirically, they 
seem to be strong enough.

Anyone know what "schedule" these pipes are likely to be and whether I 
have just been lucky or whether heavy duty fence posts are a good choice?
