That's correct.  Those two can be ganged with the two number  14s, but it 
probably won't be necessary if the cap is moved.  
 
Out in KH6 I had a 500 foot run to my 4 el 40 at 150.  With  the trades 
constantly blowing voltage drop would be an issue.  My  solution was to run two 
runs of 14-2 house wiring to the tower...for a total of  six wires.  This 
was possible since I mounted the cap at the base of the  tower.  Wiring costs 
were just a fraction of what I would have paid  for 8 conductor wire with 
two 14 wires.  My total cost was around $100 for  a 1000 foot roll of 14-2 
house wiring.  The cost for 500 ft of 8 conductor  with two number 14 wires 
would have been in excess of $500.
 
Another way to go would be to just run some cheap 3 conductor along  with 
the 14-2 house wiring.
 
As hams know...cheap is good!

Hello all, correct me if I am wrong but doesn't moving the capacitor to  
the rotator free up a couple of conductors that can be repurposed to lower the 
 voltage drop to the motor?

Two  ways to go...
Put the starting cap at the rotor , or put the starting cap  at the  
junction box below.  I simply removed the cap from the  control box and  
mounted it 
at the base of the tower...worked  fine.

I'm  using a tail twister rotor 350 ft form the control  box turning a 
2 el  quad, This problem reoccurs each winner when  the wind blows 
..Well in fact  any time the wind blows .. With the  wind 20 mph or 
more the rotor stalls ,  I did use # 14 wire on the  motor leads and I 
have a junction box at the  base of the tower  were I change to regular 
rotor cable going up the tower   .

Heres my Question, can I put a Start or Run Capacitor in my  junction  
box and still leave the capacitor in the control box ?  would this  
help?  Another  thought was , could I replace  the transformer in  the 
control box to a little higher voltage  ?

Thanks Ed
