Subject: Re: [TowerTalk] Rotator Choice for Larger Yagi
Besides adding a water shield and new clamps to the OR2800, I would
recommend a Green Heron controller. This controller will work well with
the pulse reed switch with no special cable requirements.

## toss in the Nord lock washers, and / or blue loctite.. to the list, and
you
have a winner. Im 99% sure you can buy a OR-2800 without the mating
M2 control box for it. Then just buy the OR-2800 + GH box.
## a small traffic cone will also work for a water shield, provided you paint /
cover it 1st...so it doesn’t look silly being bright red /orange. That water
shield shown on amazon will do the trick, and fit any diam mast you want.
## The K7NV mast clamp is a thing of beauty, he also uses em on his prop pitch
rotors. Forget the bolts that compress the flanges, just pinch them with
vice grips
and the mast wont budge ! Ok, now add the bolts, tighten em up a bit, then
remove
the vice grips. Mast wont budge...cant slip. Its a superb design, since it
has a LOT of surface
area. Not too many of the teeth on the oem m2 clamp actually touch the mast.
And they
wont dig into a CM mast anyway. On K7NVs clamp, even with a 2 inch mast, it
provides
> 36 sq inches of surface area. And > 54 sq inches if a 3 inch mast used.
