1.12 Backup Batteries

The NXD RAN has two backup battery options:

•Extended Batteries: provide backup protection for up to two hours. These are four 12V, 85-100 AH internal batteries connected in series for a -48V system. The four batteries together with associated wiring and hardware weigh 325 pounds (147.7 kg).

•Glitch Batteries: provide backup protection for up to five minutes. These are small, motorcycle type batteries connected in a series configuration.

1.13 Antenna

ADC provides a pole-mount antenna kit for use when the RAN is mounted on a wooden utility pole. The kit must be separately ordered from the RAN. Pole mounting is the most common type of RAN installation.

The antenna offered interfaces with the PCS and Cellular/SMR bands and supports two branch diversity receive paths. Also included in the kit is the GPS antenna used by the RAN.

The RAN may also be mounted outdoors on a concrete pad. This type of installation may use a conventional directional antenna in either a sector or quasi-omni antenna configuration, depending on the coverage objective and design. Proper antenna selection and the mounting installation are the responsibility of the design engineer.

Antenna installation is covered in separate publications, available for downloading from the ADC web site, www.adc.com. Refer to RELATED PUBLICATIONS on Page vii.
