MDS 05-3301A01, Rev. C MDS 9810 Installation and Operation Guide 7
A single-radio repeater works similar to the system shown in Figure 8,
but consists of just one transceiver at the repeater site. It works by buff-
ering (storing) incoming messages and retransmitting them a short time
later. Accordingly, there will be a delay in transmissions through this
type of repeater. Additional details for Single-Radio repeater s are given
in Section 4.5 (Page 24).
2.3 Accessories
The transceiver can be used with one or more of the accessories listed in
Table 1. Contact the factory for ordering details.
3.0 INSTALLATION PLANNING
The installation of the radio is not difficult, but it does require some
planning to ensure station reliability and efficiency. This section pro-
vides tips for selecting an appropriate site, choosing an antenna system,
and reducing the chance of harmful interference.
3.1 General Requirements
There are three main requirements for installing the radio—adequate
and stable primary power, a good antenna system, and the correct inter-
face between the transceiver and the data device.
