Running the coax will be a difficult task so I am curious about the effect of using this 75 ohm coax instead of 50 ohm. Frequencies will be 3-54mhz. I have been using this antenna but with a temporary piece of 50 ohm coax and need to relocate the feed end of the antenna which results in a much longer run was about 10'. Using 75 Ohm CATV Coaxial Cable. Most transceivers and antennas designed for ham use are based on 50 ohm impedance. The easiest way to connect your rig to your antennas is to use 50 ohm coax such as RG-8, RG213, RG-58, or my favorite, LMR-400. 1/2 Heliax Hardline, Hardline Coax Cable, 1 2 Heliax.Looking for the best 1/2 Heliax Hardline cable for sale?

Currently using RG-8X, so would it be an advantage to transform to 50 ohm or run the mismatch as is for a 60 ft run up the tower? Sure, you can use 75 ohm coax instead of 50 ohm. In some cases such as feeding a dipole, 75 ohm coax may be a better match to the load than 50 ohm. In other cases such as feeding a vertical, it may be a worse match. You may not even need to do additional matching.

ECOFLEX 15 is a new 50 Ohm coaxial cable for use in the frequency range of DC - 6 GHz. It´s unique construction combines the low loss properties found in non-flexible solid centre conductor hardline cables with the high flexability of cables manufactured with stranded center conductors. Another type of hardline frequently available is surplus CATV 75-ohm, in 3/4 inch or half-inch sizes, and some others. Before acquiring the Prodelin, I used much of this without worrying about the slight mismatch 1.4:1 SWR with 50-ohm antennas, taking advantage of the lower loss vs. coax cable. - Matching a 75 ohm CATV hardline to a 50 ohm antenn - Matching a 75 ohm CATV hardline to a 50 ohm antenna.
