1. A modular repeater comprising:
a housing having generally oppositely facing surfaces;
at least one antenna positioned on each of said surfaces for radiating energy in generally opposite directions;
electronic circuitry positioned in the housing and operatively coupling signals between the antennas, the electronic circuitry including feedback suppression structures for improving side-to-side isolation,
wherein said antennas each comprise radiating antenna elements located centrally on an associated ground plane of sufficient area within the housing to contribute significant feedback suppression.
