Hi Oded,

Dual RG-6 coaxial cable to run from the power injector to the 1300. See attached notes:

Cisco Aironet 1300 Series Access Point/Bridge Power Injector

The Cisco Aironet 1300 Series Outdoor Access Point/Bridge Power Injector,converts the standard 10/100 BaseT Ethernet interface that is suitable for weather protected areas to a dual F-Type connector interface for coax cables that are more suitable for harsh outdoor environments. The Power Injector also provides power to the outdoor unit over the same cables with a power discover feature and surge protection. To support longer cable runs from your wireless network switch or router, the Power Injector LR is designed to accommodate ***up to a 100 meter coaxial cable run*** plus 100 meters of indoor cat5 cable enabling total cable runs up to 200 meters. The Cisco Aironet 1300 Series Outdoor Access Point/Bridge ships with the Power Injector LR2 and an AC power supply.
