John,

I have a tower that tilts over and a TiltPlate. There are several VHF/UHF antennas and a mast-mounted preamp in addition to a 4-element SteppIR that is mounted on the TiltPlate. The setup has made it possible for me to work on my antennas by myself without having to climb and rig tram lines, gin poles, etc. Even without the SteppIR, which is the antenna I'm looking to replace, I'm sure there will be occasions to tilt the tower over.

Here is a link the the adapter for a 40mm square boom. Its not complicated at all:

I can't really find much documentation on the site selling the tilt plate so
I suggested shimming the bearing to make it level.  If there is another
solution - great.  I guess the you have to be sure that the elements will
clear the tower when it's tilting.  An easy option is just mount the antenna
when the tower is vertical but maybe that's not possible for you.  With a
quality rotator and quality coax and connectors, it should last for years
without needing maintenance.
