New ... ProSisTel PST-641 Rotator and Model 'C' Controller

I am selling my ProSisTel PST-641 rotator and controller. According to the label on the back of the controller, this rotator and controller were manufactured in 2002. I obtained them back 2009 and used them until 2018. As far as I can ascertain, the controller is fully functional, although I have never interfaced it to a PC, nor do I have any software for it. The actual rotator suffered a broken bottom casting in 2008. This was repaired by myself in 2009 and remained in service on top of my mast until 2018. You can read about this particular rotator in one of my posts here.

I do NOT recommend installing this rotator without lateral reinforcement, i.e. It MUST be installed within a suitable cage at the top of the mast.

Price: £250 plus shipping.

Contact me for further details.

Miscellaneous Items for sale

I have decided to clear some space in the workshop so I am shedding some surplus stock. Most, if not all of what I am selling can be termed NOS (New Old Stock).
