Re: Where do I buy this...

Don't know what happened to the original post, but that looks like some of the aluminum channel stock the local Lowe's carries.

My loco Lowe's doesn't have it that wide ;-)

Addressing just the original post issue: I don't see it either. I've see that same symptom - missing the original post - a handful of times recently. I wonder what causes that, and have no guess as to what it is.

ISP's spam blocker? Dunno, it was there in Google Groups earlier.

I found 1-5/8" drywall TRACK(*) at Atko Building Materials (in Mesa), $3.95 for 10' lengths.

Had to take my Frontier... amazing it started... it sits there for months at a time, undriven ;-)

(*) 20 gauge U-channel, but no pre-punched holes like sheet metal studs have.

$3.95 !! I bought some 3/4" aluminum U track (don't know the right name for it) at the hardware store. Over $10.00 for 6 feet. :-( I used 2 pieces to make a boom for a 6 meter yagi. Is the stuff you bought stiff enough for that if you make a rectangular boom from 2 pieces? (The elements were light aluminum 1/4" tubing.) With 10' I wouldn't need to make extensions if I ever decide to renew the experiment. I was (unsuccessfully) experimenting with signal polarization.
