Grounding antenna with rotator

[radiopro52]

I'm going to add this rotator to my scanner antenna. The only concern I have right now is grounding. The mast I have is grounded. However, the antenna will be placed on another pole on the rotor and from what I see, won't make contact with the grounded mast, leaving that pole ungrounded. The two sets of clamps on the rotor are seperated, so there's no way for the pole to make contact with the mast. So do I have to run some more ground wire from the second pole, or unground the mast and just ground the pole the antenna will be placed on? Or should I not worry about it and just leave it be? Thanks for any help.

As long as the mast above the rotator is metal, you're okay. The rotator is metal, the bearings and gears inside are all metal. No worries.

I thought the outside of the rotator was plastic or some other material, not metal. It doesn't feel like metal to me, but I could be wrong. I know the inside gears and everything are metal, but the mast doesn't touch those unless it makes contact with them through the clamps. Well, I'll just put it up the way it is then.

Got an ohm meter? Check it. Don't have one? Buy one ... always handy, often cheap. If you're not sure, then run a ground wire around it, won't hurt anything.

2 feet of copper braid (strip some rg-8) and a couple stainless hose clamps will sort the grounding issue if you're concerned about it...
