I have two unused forty foot lengths of aluminum irrigation tubing I
need to unload. One is 4" in diameter and the other is 3" in diameter.
Wall thickneses are around 0.060". A number of years ago I built
several fullsize 40M yagis for fellow club members and I used this
tubing for the booms, etc. I've been storing these "leftover" tubes
ever since but now I have to either find a home for them or scrap
them. I'll give them away gratis to anyone who will pick them up. The
4" tube would make a nice light-duty easy-up guyed tower for instance.
The location is Clifton Heights PA in the southeastern suburbs of
Philadelphia. E-mail w3rv to

Where I grew up and became a ham, there wasn't a lot of money floating
around, and most of the hams made do with whatever they could for rigs
and antennas. A favorite antenna was a 40 foot length of 4"
irrigation pipe, vertical, fed against some ground radials. It works
out to very nearly 5/8 wave on 20 meters, and isn't hard to load on 40
and 15. Most of them did quite well with it. Maybe that will give
some youngster in your area some ideas. Your free offer is most of
what they'd need for that sort of antenna.

Cheers,
Tom

That's very good application. And they don't take much room to
install.

I've seen 'em stacked end-to-end to build 40 & 80M verticals, masts to
support dipoles & rhombics, for booms like the ones I made, etc. Their
use has been limited only by imaginations. With hams being the
ingenious buggers we are there aren't many limitations.
