[TowerTalk] Prosistel PST61 Control Box problem

[Rudy Bakalov]

The video is consistent with my experience with damaged pots.

It has been a 4-year saga with the PST61D. It is rated at 36 sq.ft of wind load, but in practice this rating is just a wishful thinking.

I rotate a 4 el 40m M2 yagi and a 6 el KT36XA M2 tribander. Total wind load is within the rotator's specifications.  However, the rotator casing is not designed adequately and the two halves rotate a tiny little bit when the rotator starts and stops.

As a result, the 4 bolts that keep the two halves together elongate their holes. Further, the gasket between the halves disintegrates. The end result is water and dirt accumulating over the pot and eventually damaging the pot.

This happened to me 3 times. A very clever friend of mine found a solution where he attached brackets to the rotator enclosure and braced it to the tower legs. The enclosure no longer moves.
