Appendix A – Antenna Coverage
The RRM02 features a diversity receiver, which takes the strongest of the received signals from the two
antennae.
The diagram below shows the coverage distance with local antennae and remote antennae.

REMOTE ANTENNAE
R
is the range of ‘good’ reception for a single antenna.
R
can be up to 300 m in free air; however this figure is strongly modified (reduced) by building infrastructure.
The attenuation of the cables should be considered when remote antennae are deployed. Thicker cables
offer lower attenuation but cannot be routed inside the unit when fed through the holes located on the lower
face of the unit.
Site trials are therefore recommended to ascertain the coverage in a particular environment.
