[TowerTalk] Rotor Connector

[Steve Weisbrod]

You can buy all the replacement pins and connector parts you want from   
Digi-Key 800-344-4539 or Allied radio 800 433 5700. There not expensive.

     The connector is used by CATS and was used by Hy-Gain. They are not   
easy
to wire but do work okay when you're done. If you screw up, you need a   
pin
extractor to get the pins out. Hy-Gain sells more spare pins than you can
believe for people who have messed them up.

    I think they've changed to a more conventional pigtail and   
Cinch-Jones
plug recently because of the problems.

    The  CATS rotator end version mounts directly into the place where   
the
terminal strip used to be. It's okay except if you're using a   
mast-mounting
bracket. Then you have to grind it out so that you'll have enough   
clearance
for the plug.

      Hy-Gain uses a 12 inch pigtail.

     Please tell me you're not going to use it? If you insist, wrap   
whatever
you're working on with 33 or 88 Scotch electrical tape and THEN put the   
coax
seal on. I've seen plenty of rotator terminal strips where the CoaxSeal   
was
applied directly. What a mess.

    Be careful when disassembling the rotator for "bearing fall-out"   
because
they will.

    Once you've put the connector on, you're mostly commited to it for
subsequent rotators with that cable end.

    What you can do if you want to sell it or install it somewhere else   
is to
cut the rotor cable a couple of feet from the rotator. Then you can   
always
splice it to another cable run. Crimp butt connectors or   
soldered/shrink-tubed
methods both work.

    Personally I use the terminal strips and just replace them the next   
time
the rotator is worked on (because it will be). They're expendable and   
easily
replaceable.
