Never trusted the Rohn "push'm-up-poles"..... last two I built, I found a
metal fabricator shop who built a 60 footer out of square tubing ..four (3"
and down) pieces slide down inside each other with dual rod inserts to lock
the sections together, he even made two eyes at the balance points so I
could install a lift cable ...I then dug a hole inserted two treated 6X6's
with a three inch space between...inserted and aligned the bottom section
With a pivot rod and a lock rod...then assembled all and pulled it up with a
15 dollar winch ......
Of course I sold the home and moved, however I was in town last Christmas
and drove by the house and there was the square mast with an American flag
atop....so it's still going strong since 1978, some 30 years.....
The next one I built came from a "sprinkler company", who installed interior
building fire sprinkler pipes ..... seem he had a heck of a choice of sizes
so it was no problem getting a good in & in fit, seems they need many size
diameter pipes for pressure regulation etc....
Both system were painted with a cold galvanizing compound recommended by
both pipe companies...

That sounds about right. It's why I buy them in lots of 5 :-).
Oh yeah, OTA TV viewing is on the rise. Pretty fast I'm told. Most large
cities have a lot of channel choices and the image quality is oftem better
than cable or sat. service.

I must have missed something? The cost of the 9H50 is ~$130, however if you
look at the shipping information, it says it will only ship by truck!
Shipping cost by truck to my QTH in south Georgia is $150.00! The fine print
can get you?

Check it out, on that link you sent Mark, they sell something I've
never heard of before, some kind of special version of the H50, the
9H50, that collapses down to a length that UPS will take. Could be an
option for anyone who can't get one nearby in person. Thanks for
sending that--I never knew they made such a thing.
