Hi!

I am planing to shunt feed my rotating tower. There are four yagis on it  5el 
15m up 130', 5el 20m up 120', 4el 17m up 110' and  5 el 10m up 100'  the first 
guy wire bearing ring is up  92' and the second 46' so I must put the gamma rod 
going inside the bearing rings so it is only a few inches from the tower on 
those points  My question is what would be the best spacing and lenght for 
gamma rod to start. The upper guy wires (4) are cutted for 80 m half slopers.
