Electrical Metalic Tubing. Also known as thin wall conduit.
I used to sell and deliver the stuff.. The EMT I'm referring to, are the 3" and 4" I.D. that was threaded one end and had a built-in coupler at the other - not quite so thin. They come in 10' and 20' sections, and are not bad for weight. 3 and 4" ID tubing is much better rated for a support of some antenna, than that small thin-wall stuff you guys are thinking about. The thin stuff is the stuff that's used in some houses/businesses as wiring conduit. For more than a 20' run, that stuff can't support itself, let alone anything else.
