3.13 VHF Air Interface Shelf (50-078012)
3.13.1 Description
The VHF system is provided with three Yagi off-air antennas, two downlink, receiving downlink signals
from two different directions, and one uplink, facing the nearest BTS. Bandpass filters exclude
extraneous noise on the frequency bands to be processed and once filtered, the downlink signal is
amplified (10dB gain) and separately split to the simplex and duplex shelves’ inputs. The uplink
outputs from these six VHF shelves are combined, filtered and sent directly to the uplink off-air Yagi
antenna. The downlink low-noise-amplifier has an alarm, configured as a summary, volt-free relay
contact pair terminating at pins 1 & 2 on the ‘D’ type alarm connector.
