[TowerTalk] 5 x conductor rotor cable ?

[jimlux at earthlink.net]

Its always a trade between buying copper for a heavy gauge run or putting the power supply remote and spending less on the copper. But at the hassle of running 120v circuits.  Or just letting the losses at low voltage be and bumping the supply voltage ( the latter is why constant current type drives are nice)

I have a 450 foot cable run to my medium prop pitch and it works fine with 
the transformer in the shack.    For the motor I used three runs of 6 gauge 
house wire and for the sensor I used a cable that has two #18 conductors. 
For your shorter run I'm sure that you can find 3 conductor Romax and then 
use another cable for the sensor.

8A while running; how many amps to start?

I had to locate the 24vdc power supply at the prop pitch for a 250ft and a
700ft long run at one time. The message here is to test with the cable
before  installing.

Who  makes  5 x conductor rotor cable ?    I need 175'  for the  small PP.
   3 x BIG wires and 2 x small ones.
These small  PP's have a com/CW/CCW  for the dc motor which sucks 7-8 A .
  And 2 x small wires  for the
magnetic pulses  for the digital  readout.   Something like 3 x 12 ga's  +
2 x 20 ga's  would be ideal.  It has
to be flexible enough for a crank up.   Does it even exist ?

Tnx... Jim   VE7RF
