I had this problem years ago on a long rotor cable run. I added a small
transformer in series with the AC voltage going to the tower. I think it
was a 6 volt filament transformer, maybe 5 amps. I wired the primary in
parallel with the power to the rotor controller. Had to reverse the
secondary winding after I first hooked it up because it was "bucking" the
voltage rather than "boosting". So the extra 6 volts at the head end
overcame the resistance losses and gave me enough voltage at the tower end
to make the rotor work fine. Of course this only works for a rotor running
on AC .

Subject: [TowerTalk] help on long rotor runs??
I need ideas on a long rotor run.It's about 200 ft.I have a nre rebuilt
T2x.I tested the tower run which is about 60ft.Worked fine.I then installed
it and connected from the up the tower run to lightning protection.Gas
charged modules,I did check for shorts before connecting.I then connected
the full run.The meter goes to north upon power,which is where I left it
after first test.All lights up.when I press the brake it appears it locks
and the jumper wires get very,very hot....I presume it is a volyage
problem,voltage derop from the long run....What can I do.This is the heavy
duty cable from dxengineering..Add 2 wires of larger size 0n 1 an2 ??
ideas...
