Roger,
I have both 2800s Yasesu & Orion. Both are excellent rotators, but with
large differences in capabilities and that shows in the price. However,
if you ever need to dig into the yaesu controller, your curses towards
the designers will be without limit. Truly mickey mouse, it seems three
different engineers couldn't agree on how to interconnect three pcbs so
there are random soldered wires, connectors, and jumpers between the
boards. Then the factory schematic is scrambled eggs. There are redo's
that have been drawn that make logical layout sense. I replaced the
pointer drive belt, actually an o-ring, so if you need one, I have 90
left over after I gave away some for others to repair their rotted one.
The pointer gear train is another "interesting" design choice.
OTOH, either with a Green Heron controller is fine, but I don't think
you can buy the yaesu w/o the yaesu controller. A used yaesu rotator
plus new Green Heron is another way to go. The clean/grease/replace
balls for the yaesu is no big deal.
My Orion was a very tight fit in the HDX589, and the yaesu went easily
into the other 589.

Jim,
I replaced a T2X Tailtwister with a Yaesu G-2800DXA and other than
rewiring the plug on each end, I had to change nothing at all. The
fit was perfect. I do use a thrust bearing to carry all of thee
weight of a Force-12 C-4XLD on a Hy-Gain HG-54HD crank-up tower.
I checked the catalog and the G-2800DXA is rated to support 661# of
vertical load so the thrust bearing only needs to remove the leverage.
There is no need for the thrust bearing to support any of the load if
its less than 661#.
I'm thinking of using the Yaesu G-2800DXA or the Orion 2800PDX which
will support "1800" pounds and has 17,000" pounds of torque.

Good luck in your endeavor.

Subject: [TowerTalk] HAM IV Height
Greetings,
I'm replacing a HAM IV with a Yaesu G-800GXA and concerned about the
depth
of the mast into the rotor housing.
What is the dimension on the HAM IV from the mounting plate to the point
that the bottom of the mast rests?
