1. [TowerTalk] Rotator mast mount (score: 1)

Anyone have any recommendations for mounting a Ham IV atop a 2" mast section. I'm building a standoff mount on one of my towers for a 3 element SteppIR. I've got some 2" angle iron that I'm going to

I would strongly suggest a thrust bearing be mounted above the Ham IV even though side mounted. The SteperIR would be a heavy load on the rotator at the top of a tower, let alone on top of a 4' mast

This might be a silly question, because I'm not familiar with the Ham IV - but how do you avoid having a senior moment and trying to rotate it too far ? John G4ZTR Anyone have any recommendations for

Hello Guy - You don't want a mast mount for your rotor. Use a couple pieces of angle coming out from a corner of the tower and mount it directly on them. It's best to do it a a section joint using he

I agree with Roger. the 3el SteppIR is a lot of wind load for a Ham IV without a thrust bearing. Look at the W9IIX RM-16 Antenna/Rotor mount for an idea of how to do this: http://www.w9iix.com/ii0001

I've used a "swing arm" arrangement made of pipe, pipe fittings, steel tube, and saddle clamps that take the "tilt" or leverage off the rotator and gives close to, or even more than 300 degrees of ro

That's just about the same as I did with the "plumber's delight" construction except with a larger tower I mounted it farther out giving me about 340 degrees of swing. Limit switches can be programme

For what it's worth, I think a much better design is that by Custom Metalworks, because it spreads the load of the side-mounted stuff to all three legs instead of just one. Easy to reverse-engineer f

Pete, thanks for pointing out the Custom Metalworks side mount. I wasn't familiar with that one, but I agree that looks like a much better solution, especially for a heavy yagi like the 3el SteppIR.

The Green Herons will let you set stops. Put big black lines on the display as do not cross lines. The rotor turns so slow you probably would have a tough time damaging the tower but your milage may

If the rotator OR antenna ever slips on the mast (and who hasn't seen that happen) you are screwed. It might be worth putting limit switches on the tower that contact the boom just before a collision

For what it's worth, a Ham 4 rotator does not mind being *stopped* once in a while (a strong wind will stop a long boom yagi from being turned by a Ham 4), and it does not have sufficient torque to d

Bad design. (I had one). Only bolts onto one leg. Better design is a side mount that bolts to 2 legs. MUCH less stress on the tower legs. 73 Jim W7RY _______________________________________________ _

First the design is a very simple one, and like Jim I suggest the two leg design. It is possible to exert a twisting motion on the side of the tower if the all the bolts are not tight, or the system
