PREFACE

The Wireless Antenna WX-RP921 is designed to be
used with the Diversity Receivers WX-RP810AVX-

RP820 and Distributor WX-RP900. It is equipped with a
built-in down converter from

OOMH

to 260MHz to

minimize cable loss,

FEATURES

• 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.

PRECAUTIONS

• The Wireless Antenna WX-RP921 is designed for

indoor use. Do not install it outdoors,

• Always install the wireless antenna with mounting

bracket (provided) vertically.

• Do not place the receiving antenna in places

affected by strong electrical or magnetic fields,
such as near AC power lines, motors, transformers
or generators.

• Do not place the wireless antenna near metallic

materials, as the receiving sensitivity of wireless

antenna will be reduced.

• Place the wireless antennas between 16.7ft (5m)

and

ft (

m) apart from each other for the best

diversity effect.

• Do not place the wireless microphone less than

6.7fi (2m) apart from wireless antenna. Otherwise

interference noise will occur.

• Always use high quality cable. Low grade cable

will cause signal loss and interference.
