    Ouch - a recipe for disaster. Pipe - the  definition of which has been 
recently discussed - is not rated for strength  and is heavy but not strong 
enough. A typical water pipe might have 35,000 psi  yield strength. You're 
probably going to need more than that; e.g. 50-60,000  or more. 
    You didn't mention your local windspeed rating.  If you don't know, you 
can find it on _www.championradio.com_ (  under 
"Tech  Notes". 
    I sell the MARC Program - the Mast, Antenna and  Rotator Calculator - for 
ten bucks on the same website. It'll give you the  info you need. And you 
need tubing - not pipe.
