Typically frequencies up to 500 MHz to 1 GHz. Those systems use baluns on both ends of cable and also often suitable amplifier on sending end that boosts higher frequencies more than lower.

Claimed to work well with shielded cables (shielded cat6 or cat7). With unshielded cable more variation with performance.

I am doing something similar for a planned RF over twisted pair product I would like to build. Have you ever seen anything on transmitting cellular band or Wi-Fi signals over twisted pair? Maybe the differences between Cat-5e and Cat-6/6e. I am working on a PoE model over the same cable 2 wires for Tx and RX each and the other four for DC power.
