I had some C-band positioner cable that had all the wires I needed for
direction indication and a pair of #10 or #12 (R&B) wires to drive the
motor along with two RG-6's all molded into the one cable. You might not
have any use for the FG-6, but it was cheap and rugged. With so few of
the BUGs (Big Ugly Dishs) around any more they stuff may not be
available or it may be a lot more expensive. I don't know, but it might
be worth checking into.
