Point to Point Repeater

Radios may be wired as back-to-back repeaters, to extend the range of a point-to-point system. The

modems are not configured as repeaters (in

the menu they configured in Point to Point

Mode) but are wired together as back-to-back

repeaters.

Figure 9-3 and Figure 9-4 depict how a link

might be set up using a repeater. The repeater may be sitting on a hilltop or other elevated structure to link

the master to the slave. In this configuration it may be desirable to use Yagi antennas to extend the range

between the Repeater and either or both the Master and Slave.

Figure 9-5 shows

a link with two

repeaters between the

master and slave.

With two repeaters

there is clearly more

flexibility in getting

around obstacles and

greater total range is possible. Once again, it would be desirable to use external omni-directional antennas

with the repeaters, and attaching a Yagi to the master and slave would increase the range of the link. When

two repeaters are used there is no further degradation in the RF speed of the link, only the data latency is

affected.
