AP 1310 - distance from Power injector

Answered Question
Mar 7th, 2007

I need to place my 1300 antenna some distance away from the power injector.

Is there a distance limitation on the 2 coax cables connecting the antenna to the power injector?

I have this problem too.

Hi John,

The distance limitation is listed @ 100 meters.

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

Cisco Aironet 1300 Series

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.

Ethernet Ports

The access point/bridge dual-coax Ethernet ports consists of a pair of 75-ohm F-type connectors, linking the unit to your 100BASE-T Ethernet LAN through the power injector. The dual-coax cables are used to send and receive Ethernet data and to supply inline 48-VDC power from the power injector to the access point/bridge.

Power

The access point/bridge receives inline power from the Cisco Aironet Power Injector (hereafter called the power injector). Dual-coax cables are used to provide Ethernet data and power from the power injector to the access point/bridge. The power injector is an external unit designed for operation in a sheltered environment, such as inside a building or vehicle. The power injector also functions as an Ethernet repeater by connecting to a Category 5 LAN backbone and using the dual-coax cable interface to the access point/bridge.
