[TowerTalk] Rotator cable

[Roger K8RI on Tower]

Why not make up your own using THHN, or MTW?  It's *relatively* inexpensive, 
comes in a wide variety of sizes.  I think #14 is the smallest with the 
largest being at least #10 or even #6.

Check with the C-Band suppliers. The dish positioners use #10 or #12 for 
power and smaller wires for the positioning pulses.  Those cables have an 
additional pair for the polarization rotator as well.
