I'm wanting to purchase and install a base antenna for 10-12 meters. I have a 2 ft. Triangular,31 ft. Tower I made out of 1/2 inch. and 3/4 inch. rigid electrical conduit. It has a rotor driven mast coming out of the top of it 6 ft. It has a stacked pair of long DX tv log periodical antennas at 32 ft. and at 36.6 ft. . A stainless steel 102" 1/4 wave whip is mounted at the top of the mast with no coax attached. The mast is 1 1/2" plumbing pipe(withstood Hurricane Floyd)and has a tv rotor rotating it. It is approximately 65 ft. From the bottom of the tower to where a base station radio would be hooked up. The tower is anchored to a 9000 lb. poured block of concrete using three,one inch diameter,three foot long galvanized threaded rods. The tower is free standing. How long and what type coax would be appropriate? I want as low loss coax as I can get. I'll be using a legal power rated radio,no amps.P.S. the coax will be buried.
