Greetings all, I've been having a continuous problemw/my tower setup since installed in 1993'. I just can't figure it out. I've mentioned this online in the past, & received much helpf/hams/clubs &
Dave, I have had problems with the T2X's also. They would get stuck in one position and wouldnt turn.Sometimes I could momentarily turn it in opposite directions and sometimes would be OK.I found o

Dave, Sounds like you need more rotator. The delay on the brake should help, give time for the amplitude of oscillations to dampen before engaging. If the rotator still dies early even with the brake

An item not discussed much is the mechanical resonances in tower + antenna systems. I see this on my big tower when the 20m5L top moves and causes oscillations in the bottom 20m5L. This is with doubl
Don't forget to see that the mast is centered properly in the rotator. The T2X is designed for a fixed size mast, can't remember the diameter. If the mast is not the design size you need shims betwee
The Mosley 57B is does not appear to be a large antenna so you should not have this much trouble. I am not sure what alignment issue you think you may have. If you are just using a thrust bearing and
I've always thought that in some situations the slop between the sections in crank-ups is NOT friendly to rotators. The antenna comes to a sudden stop up against the UN-moveable bottom section, where
The typical HAMIV and T2X rotators have 3 separate systems inside them. A 500 ohm potentiometer to determine position, a motor and gear box to turn the thing, and a brake solenoid that pulls a brake
Over the years there were at least 2 different brake designs for the bell housing type rotors from CDE / Hygain that used a brake. The older wedge was a V tip while the newer design is a rectangular

If you read the manual for both T2X and the Ham-M series, you will see quite a thorough discussion on the absolute necessity of shimming up any mast that is not to their specs. I use 2" masts, so a t
Regarding the sticking brake: The Green Heron control box will attempt to turn very briefly the T2X the opposite direction from the desired rotation to assist getting the brake free. It was done beca

I have not owned a Hy-gain rotator in decades, I remember shimming one but that was for 1.900 od water pipe. So I just looked at the manual and the T2X is designed for a 2 1/16 mast. I am not sure wh

This almost has to be an alignment, or bearing problem unless you have a snagged rotator cable problem. Even a snagged RG8 size cable is strong enough to hold a TailTwister. I had a Ham IV under this
