2 Site Requirements
2.1 Site Environment
The site environment for the NC-2202 should be a clean environment with adequate space and lighting to allow for the
equipment to be serviced. The room should have a heating, ventilation and air conditioning (HVAC) system to maintain the
room temperature within the operating temperature range of the NC-2202, -30 to +40 Celsius. If necessary a cabinet cooling
option can be ordered for the equipment cabinet which will extend the upper operating range to +60 Celsius.
2.2 Space Requirement
The NC-2202 Cabinet is a 19” EIA equipment cabinet with outside dimensions of 74”H x 23”W x 33.5”D with the doors on.
The cabinet has locking front and rear doors. A minimum of 24” of clear space should be provided in front of and behind the
cabinet to allow access for servicing.
2.3 Primary Power Requirement
The NC-2202 requires a dedicated 120VAC 15A circuit. A duplex receptacle should be located within 6’ of the cabinet.
2.4 Grounding Requirement
The site should have a proper grounding electrode system designed to the standards described in the Motorola R56 Standards
and Guidelines for Communications Sites. The NC-2202 rack ground bus (RGB) should be bonded to the master ground bus
(MGB) of the building using a #2 AWG green jacketed stranded copper ground wire.
2.5 Antenna System Requirements
The typical antenna used for the NC-2202 is the RFS Celwave 220-8 antenna. This is a 6 dBd omni fibreglass antenna. The
antenna is typically side mounted on a tower with a Celwave 561 side mount kit. Other antennas and mounting arrangements
may be considered. The minimum mounting height for the antenna is 15 meters above ground to ensure that no persons
walking within proximity of the antenna are exposed to harmful radiation.
The typical antenna transmission line is Andrew LDF5-50A 7/8” Foam Heliax. This cable has approximately .5 dB loss per
100’ at 220 MHz and is recommended for cable runs in excess of 100’. Other low loss cable may be used for shorter runs.
Andrew LDF4-50A ½” Foam Heliax has approximately 1.0 dB loss per 100’.
