I've put up PVC pipe to about 35 feet, using pretty simple guying. If
you used more complicated guying and keep the wind load at the top
very small, I'd think you could get to 50 feet that way. I used
telescoping sections, 10 feet each of 2", 1-1/2", 1" and 3/4" as I
recall, with a couple feet overlap at each junction. Use 20 foot
sections and maybe start at 2-1/2", perhaps. You can use couplings
turned on a lathe, glued to the bottom of each upper section, to make
a nice sliding fit. Be sure to use enough guy points to keep the
thing straight! Use UV-resistant materials if you want it to stay up
for a while: electrical PVC conduit is generally sunlight-resistant.

You can also get telescoping fiberglass tubes (sold for quad antenna
"spiders") that might get you to that sort of height, with guying and
some ingenuity.

Cheers,
Tom

I'm trying to do a point to point 802.11b connection to two friends
houses. This will be my 5th personal installation for wireless point to
point. I have trees in the way on both sides, and need a cost effective
way to get these antennas up 50 feet.

Does anyone have any suggestions for accomplishing this?

Thank You,

Mike Sims
