[amsat-bb] Source for 3" (76mm) pipe for dish mount?

[Scott]

Greetings!

I was fortunate enough to given a 100cm dish to play with but the mounting 
bracket requires a 3" (76mm) pipe.  I need about a 1 meter length.

The dish is a bit too heavy for me to use commonly available PVC pipe... I 
have to wonder if there is an industry that I should be looking at to find 
metal pipe of that diameter.  Metal pipe is somewhat rare in the plumbing 
world these days - I wonder if others have had luck with suppliers of fence 
posts, signs, or some other industry.

Of course, if there is a place to buy pipes intended for dish installations, 
all the better.

I'm just looking for something that I don't have to take out a bank loan to 
purchase.  Free is ok, too!

Appreciate any suggestions - I'm located in the U.S.
