3.3 REPEATER
3.3.1 General
The Repeater is designated to either extend transmission range up to 10 km (6 miles) or to
enable transmission when LOS cannot be established between the antenna and the
transmitters. The repeater should be positioned in a strategic point, providing best LOS
between it, the base station and the transmitters. A suitable place could be for example an
elevated terrain (such as a hill) or on a high pole. Each repeater has a four-digit ID number,
which enables its identification in the system by the Radio Manager
TM
.
3.3.2 Specifications
There are two types of repeaters, distinct by their power supply: mains or solar.

conditions in the area where it is placed.

• Minimum requirement for solar panel: 10 W and a battery 7.5 Amp/hour (depending on
radiation factors). For repeater operation at low radiation times, higher capacity solar
