RF CABLE INFO

You might start here:
Key factors to consider:
Characteristic Impedance - this should match the impedance seen at each end of the cable, or else you will have increased reflections and loss.
Loss - Loss is a function of cable length and signal frequency. The higher the frequency, the greater the loss. Loss is typically expressed in dB per unit length. At higher frequencies, you can easily lose most of your signal in the coax. Low-loss coax is always more expensive, and generally larger in diameter.
Application - If you want to run outdoors or underground, you need a cable rated for that service.
Hope that gets you started. You might post followup questions just under antennas group.
