ERP is the effective power in the mainlobe, so an omni antenna and a highly direction one with the same ERP will sound as loud to their intended listener. Those frequencies are used for terrestrial microwave backhauls. They're almost certainly working on a system to connect disparate fiber networks via microwave. Higher power means lower bit error rate after all.
