I have the Tashjian 4 section 72' motorized crankup, with 18 feet of .25"
wall 2" mast sticking out the top, either 2 or 3 antennae mounted,
depending. Even fully nested, the antennas are good for casual use. In the
configuration I call "half-nested" which has the bottom of section 3 at the
top of section 1, and the bottom of section 4 at the top of section 2,
therefore the top about 48 feet up, I have full overlap of sections for
extra windload capability, and the top antenna is about 65' high. (My top
antenna is a 40M dipole, the middle and lower are 10-15-20 various
combinations, depending.)
I only extend full height for contests, with a careful eye on the weather.
My system is not big-gun competitive, but I have a lot of fun with it.
The tower base was professionally done by a company in central Texas. I
wouldn't consider trying to do it myself. Too much risk.
I would do everything exactly the same if I were to do it again. The next
significant upgrade would be to grow a tower to about 100', or go to
multiple towers, and for me the cost was not worth the expected gain. And I
can work at the top of the retracted tower from rooftop-- makes a great work
platform for this OF, a great safety plus. If I strap myself to the mast I
can reach up to lower the middle antenna down so I can work on it or the
bottom antenna from rooftop. The only antenna I cannot get to is the top
antenna-- I need to rent a cherry picker to get to that one.
Oh, and I have had good suppport from Tashjian.

Rusty, na5tr
