Hi Ron: I am facing a similar problem here with an Orion rotator on a
131 ft crankup tower 250 ft from the shack. The instructions with the
Orion say use Nr 18 up to 125 ft, nr. 16 for 125-200 ft, nr. 14 for
200-300, and nr 12 for 300-450 ft. You, of course need only 2 large
conductors for the motor power and 2 small ones for the reed switch
pulses. Texas Towers, Davis RF, Cablexperts, and The Wireman all have
suitable cable with 2 large and 6 small conductors. I plan to use the
2/Nr 14, 6 Nr 18 up the tower (150 ft.). For a prop pitch I believe you
could use the 2 nr 12, 6nr 16 stuff. I will use several type UF
buryable house wires for the run to the house from the tower base. Home
depot has 3 wire Nr 12 for about $29/250ft. I will have 2 of these 3
wire cables plus several UF nr 14 3 cond which is about $22/250ft in
PVC pipe buried with drain holes at the low point and a gravel bed
beneath. The extra wires will allow for a possible ring rotor and vac
relays for switching 80m ssb to cw bands.
We have a problem here with gophers chewing buried cable. I have
personally dug up a chewed up UF cable with enough leakage to trip the
GFI and a RG59 which was chewed up so bad that the shield was open
circuited (I swear that is the truth).
