[TowerTalk] Boom-to-Mast Tilt fixture

[Bryan Swadener]

Alan,
 
I'm able to tilt my US Tower TX-472 tower over with my Force12 C-4XL on it, in one of two ways
w/o a tilt fixture...
 
The yagi boom is 30' long.  With the use of a 12' step ladder, I'm /just/ able to reach the u-bolts
on the boom-mast clamp, loosen them, and turn & tilt the yagi as needed. See photos at
http://www.tinyurl.com/wa7prc-tower.
 
The yagi boom is in five equal-length sections.  With the tower tilted over, I'm able to access
the hardware to remove/install sections of boom + element(s) as needed and continue to
lower the tower using this method, I highly recommend finding some way of preventing the
mast from rotating. My rotator has a brake, or I can use a section of angle stock drilled
to accept u-bolts that temporarily connect the mast to one rail of the tower. I used the
latter when I needed to work on the HDR300 rotator w/ my feet on the ground.
 
The above is what you do when you don't have a tilt-plate. Maybe it's not so purty but,
they work for me.

In the recent past I saw ADs for a tilt Boom-to-Mast fixture in CQ and QST which allowed a
beam to tilt so that elements were vertical an thus made it easy with a tilt-over tower to get
all on the ground for work. Does anybody have the contact info for the company that made
these since the AD is no longer in the mags.
Thanks and 73,
