PRO.SIS.TEL. ANTENNA ROTOR  PST2051-641 NEVER INSTALLED OR USED -  NO CONTROLLER

Description

PRO.SIS.TEL. ANTENNA ROTOR PST2051-641 NEVER INSTALLED OR USED - NO CONTROLLER.  COMPLETE WITH DETAILED SPIRAL BOUND MANUAL
Up for your consideration is a PRO. SIS. TEL. mod. # PST2052-641 antenna rotor.  This sale is for the rotor unit only.  This is a very heavy duty antenna rotor that is Italian made.  This is a very well known and used brand by hams that need and wish to use the very best of rotators that are available.  I would refer you to the Array Solutions web site for a full view and detailed description of this and the other PRO. SIS. TEL. rotor line.  This model lists for 5.00 plus tax.  I offer that at this price and free shipping for a unused model PST2051-641 is a very good price - as long as you can live with the chipped blue paint!!  Some of the larger ones go for thousands of dollars.  Some of the larger ones are also used on US Naval ships.  It is "very" solidly built rotor and has a worm drive.  It would need a controller unit for operation - Green Heron Electronics make a very nice digital one and I believe PRO. SIS. TEL. also makes one.  You could check for recommendations from Array Solutions. I did notice there is a matching control unit for sale (Green Heron I believe) listed on eBay.  I purchased this rotor as a intended club project for use on a cart mounted crank-up mast for EMCOM work - the control unit was never purchased and the club was not able to go thru with the plan to build the mobile EMCOM cart.  As stated this unit was never installed or used in any way.  When describing and taking the photos I wanted it to appear as it actually is - there is some of the blue paint that has chipped off showing the white undercoat used by the factory.  This is just storage/shelf rash.  It has always been stored indoors in my garage.  You will also notice that there is a photo of a short (22" long) carbon steal tube flanged on one end.  This was originally intended for mounting the rotor to the planned EMCOM antenna cart - you can have this free if you would like it
BUT you will need to pay the shipping for it
.  It is one tough 2" dia. tube should you want/need it.  If you have any questions please ask.  Thanks.  Here are some specifications for it:
