1. Three #10 wires from the control box (the motor and  brake wires, terminal 
strip wires 1,2 and 3)
2. Relocate the  motor starting capacitor to a convenient much closer to the 
rotator.  Its  not necessary to place it immediately next to the rotator.
3.  Mount a small transformer on the back of the control box and wire it  
into the control box to boost only the brake  voltage.

A cheap solution for long runs that I've used with success is 14/2  house 
wiring.  On moderately long runs I've used two runs of 14/2  wiring...giving me a 
total of six wires leading to the rotor.  For the  Tailtwister/HamIV series 
this is all you need if you mount the starting cap at  the rotor.
 
For the longer run I have with my present situation (about 650 feet top the  
top rotor) I use three runs of 14/2.  I double up the black and white for  one 
lead, another black and white for the second motor lead and use  the 
remaining three in the third and one of the grounds in the doubled up  wire four the 
fourth lead.
 
I've used this last combo for over a year and the 4 el 40 rotates well,  even 
in the heavy trades we have out here.
 
As far as cost, even with the inflated prices out on the Big Island,  the 
cost was around $275.
