[HamWAN PSDR] Need Power High on Tower

We hope to put our HamWAN Sectors up at about the 500 foot level on a commercial tower. CAT-6 is limited to 330 feet; then it needs to connect to an active component to then break out a line(with PoE) for each Sector Device(Up to an additional 330 feet). Have any of you put your equipment higher than 330 feet on a tower? How did you get the power up to the Midway device to power the second set of 330 foot PoE lines? Ideas??? 73 Ken Tolliver K7ICY
