8571—Overview and specifications
Overview
The split-site remote control NGT system provides flexibility in meeting the needs of the
customer and site requirements.
The system provides access to all NGT functions, including channel scanning and
selective calling. The operation of the split-site system is transparent to the NGT user
following installation and setup.
The split-site remote control NGT system enables you to split control, transmit and
receive functions of an HF radio system into one of three basic configurations:
•
•
•
In all of these configurations, there is a master control site and a slave site (up to four
slave sites for the remote split-site transmitter and receiver system). The master control
site is connected to a slave site via a 2-wire land line, or a 4-wire VHF/UHF
radio/microwave link. Line loss and equalisation adjustments are made automatically by
the system when requested by the user.
