Concur. Took too many tries to get an Orion 2800 into my HDX 589
without contacting the cross bracing on the way up. It looks symmetric
but it is not. Turns a DB36 & 86' dipole.
My Yaesu 2800 did fit w/o difficulty IIRC in another 589. Turns a 4L
steppir, at lot less mass and windload than a DB36.

AFAIK, the M2/Orion is the only rotator that can
fit within a UST #4 section AND also has the
strength to turn a DB-36. It is entirely possible
to fool yourself and mount a rotator into a tower
thinking it will work, only to have a problem
of interference during rotation or extention.
Been there, done that.
There is also a possibility that a cross brace
is bent inward enough to catch on the rotator.
My used HDX5106 at some time (not sure if before
or after I bought it) suffered a bent brace, limiting
its height to 70 feet. I had to build a special jig
to bend it back out using a bottle jack.

To be more specific . . . my former Ham IV motors (too weak for my 4
EL Stepir) and my current Yaesu G-2800 both fit the TX-472 rotor
mounting area w/o interference in crank-up/down. However, for example,
a Hy Gain Tail Twister will not fit and allow full crankup/down of the
tower. So, what rotator are you using? - Alan K9MBQ
