1. How does the gate operate? What powers the gate?
2. a capacitor or a battery at the gate can be a great source of power. Long cable run can trickle charge it and plenty of Watts will be available for the local devices.
Honestly, I think it would be best to use a battery at the gate with trickle charge on two pairs and use the other two pairs to trigger a relay. Unless the battery goes totally dead and the charger is suddenly activated, the two pairs of wire should be enough but I would also make sure their capacity can't be exceeded. For that reason, I think I would try to use a solar cell to charge the battery. I would be more comfortable if I could use the Cat5e for one purpose, rather than two.
