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_ (http://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.
