strong rotator Time Owned: more than 12 months.
Using a PST-61 to turn a OPTIBEAM 4-12 antenna I had no problem. Great assistance.

Never more PST rotators Time Owned: more than 12 months.
I have had a PST 2051 for about 10years and it's the worst rotor I've ever had !!! this morning for the 3rd time it went haywire ...... always the same potentiometer that allows the right reading on the digital control box. I had changed it 2 years ago ...... bad quality! I know many others people have a same experience....
I have always carried out routine checks and maintenance but it is useless. I have 2 HAM IVs on 2 other towers, one with a 2 el yagi x 40mt and the other with a Skymater Cubex Mark III 5B that are 35 years old never a problem. As soon as I have time I take it down and I don't want to know anymore! Never again

No problems Time Owned: 6 to 12 months.
Using a PST-71 to turn a 400 lb JK2040 Phantom antenna (4 full size elements on 40M and 5 elements on 20M) with a Green Heron controller. Works just fine, no problems. A little tricky getting the controller set up but otherwise great. You will have to modify a Rohn 55G tower to get this rotator to fit.

Overall a good design Time Owned: 0 to 3 months.
I recently helped NR5R replace his older rotator that needed some maintenance. After examining the product it is noticeably better than AlfaSpid and dramatically better than the Tail Twister types.

This unit was connected to a Green Heron controller. There were a few couple of issues with Green Heron's configuration documentation, but once the bugs were worked out the combination worked flawlessly.

Documentation from ProSisTel was short, simple, and to the point. It reads as if it was written by an engineer, and so could be a little "friendlier", but I had no problems with it.

System design is top notch. With one exception noted below I could not think of a better design with this size components.

Build quality appears perfect. No flaws noted.

Operation was flawless. Pointing accuracy was tested by pointing in one direction, sighting, setting the controller for 180 degrees away, sighting, then rotating back to original position and sighting. Couldn't see any errors and so would say better than 3 degree accuracy. In the air tried several positions and all matched a compass visually.

The one potential problem with the design is that the motor sticks out so far. In this case it was installed in a jack up tower and it extended outside the section which prevents the tower from being fully lowered. The antenna is still below the roof line at this point and so should be protected from extreme winds but does make working on the system more difficult.

PS 71D Very cost effective Time Owned: 0 to 3 months.
I have a very large array of antennas and needed a hefty rotor. The Prosistel 71D is rated at 90 Sq Ft, yep you read it right ninety square feet.

So, looked into a bunch of the higher capacity rotors. Prop pitch was ridiculously expensive when you also consider the cable you need man, simply not what you want to do. The 71D was very very cost effective and carries a staggering 2000 lbs of stuff! Amazing to look at this thing too, its not gigantic like a prop pitch would be and weighs a ton less. Installation was a snap, you can use good quality rotor cable not no.10 AWG as would be required for Prop pitch.

Array Solutions installed the 500 ohm pot which provides higher resolution for rotation.

Mine is sitting inside a Rohn 55G tower on a DXE rotor plate. I did have to drill four new holes but no big deal there.

Installation with a Green Herron RT 21 was a breeze to say the least.

Can't say enough about the build quality its really solid, I won't be dealing with my rotor anytime soon that is for sure!!!

PST71 Time Owned: more than 12 months.
Nothing but good things to say about this rotator. The PST71 sits atop a AN Wireless 60 and turns an Optibeam 12-6. I'm in a high wind area atop a ridge where local code requires me to have the setup rated for 130Mph gusts! Fortunately I haven't had those. That said, plenty of other Pacific NW storms have passed and everything still, maintenance free, operates as on the day it was installed. I use a Green Heron controller.

Definitely would recommend it and buy one again.

PST61D Time Owned: more than 12 months.
I have 2 PST61D and have the same probem with 2. The problem is the issue of the rotor shaft having a wearing part and soon means 10/20 ° on the mast of the antenna, and the movement and wind, have this movement of the rotor, the antenna mast wears a problem of fall of the radiant system. . . . . 1 rotor sent it to the manufacturer (Monopoli IT) and was not fixed and the 2nd I have sent the representative of Spain PROSISTEL and I say they have to buy a tool to fix it.
It is inconceblible, poor customer service by a simple repair by the manufacturer, and ditribuidor in EA (Spain) has bought a tool to solve the problem,

I have a rotor PST 61-D from a year ago and has not given me any problem, it is very robust in my area and strong winds blowing hang a trouble-free antenna Optibeam OB16-5.
Rotor is a totally recommended.

PST 61 Time Owned: more than 12 months.
I had the older AC model since 2003. In June 2016 it started acting erratic and then the potentiometer failed. Other than the pot going never gave me any problems. Replaced it with a new DC motor version.

Destructive Time Owned: more than 12 months.
My Big Boy has been in service for about 5 years. This morning it decided NOT to stop any more. Result: coax cables broken... and of course no contest this weekend and the next few weeks.
Is it to much to expect some kind of safety to avoid this from happening?

Looking good... Time Owned: 0 to 3 months.
Recently upgraded from the 61 to the PST71 as I am about to put up a larger beam. The 61 casing has a rubber "O" ring on the end of the motor unit which is supposed to stop water gaining access to the motor housing, as well as having two tiny seals on the fixing screws. I found that all of these seals had hardened and allowed the ingress of rainwater and the inside of the housing was a mass of rust, fortunately, the upgrade was done just in time to save the motor from possible damage. If I had one of these units and it has been installed on the mast for a year or more, I would make every effort to check it out. The PST71 does not have that feature, the end is permanently sealed and it would appear that it is 100% water tight and should remain that way. I like it, although climbing up a 32' ladder with the rotator on my shoulder was no fun, I am approaching 66 years of age and my xyl was not best pleased with my balancing act. I have controlled my PST61's and my new PST71 using the PST Rotator programme which I can't fault, also reviewed on eHam by a number of operators. 73 John www.gm6tvr.net

PST 2051 finally gave up the ghost during the early December 2006 gale force winds. Awarded 4 out of 5 because it was handling a 4ele SteppIR when disaster stuck. Back to the drawing board, Cheers, John
