An apparatus for limiting shadowing of RF coverage areas around antennas and closely associated equipment housings is disclosed. The equipment housing and antenna are located in close proximately such that the RF coverage area of the antenna is partially shadowed due to signal blockage by a face of the equipment housing or other structure. The shadowed RF coverage area is eliminated or substantially reduced by placement of a reflector to reflect emitted signals from the antenna into the shadowed RF coverage area.

Antenna having improved blockage fill-in characteristics

The present invention provides a system for simulcasting and diversely receiving radio frequency (RF) signals. The system of the present invention comprises at least one RF transceiver and a plurality of RF units each including a transmitter for simulcasting an RF signal to a user and further including one receiver which is paired with another receiver in another one of the RF units, the pair of receivers providing for diversity reception of an RF signal from the user. The implementation of diversity reception with only one instead of two receivers in each RF unit, as taught by the present invention, reduces both signal loss and required cabling in the system.
