How far can the antenna be located from an OMNEX radio?
Generally 200 feet is a practical maximum. Like all cable, as the length of your coaxial RF cable increases so does signal loss. Similarly, there are several types of coaxial RF cable which vary in attenuation properties depending on quality and price. Rule of thumb: running antenna cable is very similar to running 120V wire, as the length increases you must increase the cable diameter to compensate for the voltage (signal) loss.
