Hello, I'm thinking of installing some co-phased RG-59 A/U into my cb radio in my big rig.
Since RG-59 is 75 ohms or 72ohms and the SO-239 connector on the radio is 50 ohm impedence, I was wondering what the best way might be to match the antenna and coax impedence to the input of the cb radio.
Maybe a transformer or trasmach, or antenna tuner? Or could I have the coax a certain length so that it matches the 50 ohm impedence where it connects to the radio?
Also, do any companies make 75 ohm antennas?
Hopefully someone can help. Thanks.
