Panasonic RAMSA WX-RP921 Operating Instructions Manual page 4

PREFACE
The Wireless Antenna WX-RP921 is designed to be
used with the Diversity Receivers WX-RP810/WX-
RP820 and Distributor WX-RP900. It is equipped with a
built-in down converter from 800MHz to 260MHz to
minimize cable loss.
FEATURES
e The WX-RP921 includes a pre-amp which boosts
the antenna signal to compensate for coaxial
cable loss between the antennas and diversity
receivers WX-RP810/WX-RP820. It prevents dis-
ruption of the voice signal due to squelch and a
reduction in the signal-to-noise ratio caused by
dead points.
+ A phantom power supply system is employed to
supply DC power from the Diversity Receivers WX-
RP810/WX-RP820 or Distributor WX-RP900 to the
Wireless Antenna WX-RP921 via a coaxial cable.
