4.0 INSTALLATION PLANNING
Advice for planning a complete radio system, including site and antenna
selection, can be found in the Installation and Operation Manual sup-
plied with your transceivers. This section covers planning for the instal-
lation of an individual Redundant Transceiver Chassis, and for
configuring a Redundant Transceiver Chassis for use as a repeater.
(Individual transceivers may also be used as repeaters, and this informa-
tion is covered in the transceiver’s Installation and Operation Manual.)
A Redundant Transceiver Chassis (Section 4.1) is typically used at a
master station to ensure uninterrupted receipt of data from remote
radios. Although a single transceiver is most commonly used at remote
sites (Section 4.2), a Redundant Transceiver Chassis may be used for
increased reliability.
Redundant Transceiver Chassis may also be used as repeaters in a
repeater-assisted system (Section 4.3). A repeater re-transmits data
between systems, overcoming the range limitations of individual radios.
