Handling High Frequencies is something we have to do with big rigour. Is not possible, for example, to use audio coaxial cables to transfer the signal generated from the access point till the radiated antenna. If you do it, your RF signal will never be radiated!
For any specific frequency range you need a specific cable; the same is true for connectors.
In this area you'll find only cable suitable to convey high frequencies. Their very low loss per meter and their controlled impedance will assure the best performances.
