Notes on Antenna Installation
• Use a pair of antennas. Separate them by 1 to 2

meters (3

feet). Mount the antennas so that

a wireless microphone or transmitter can transmit
signals directly to the antennas.
• Do not install the antennas in the following
locations:
– inside the ceiling or walls
– near windows, metal boards, or electric equipment
(lighting fixtures, motors, elevators, breakers, etc.)
electronic equipment (computers, dimmers,
televisions, TV cameras, etc.)
– where people or other equipment might interfere
with them

Antenna
Mount the antennas more than 10 centimeters
(4 in.) away from the ceiling or an adjacent wall.
Mount the antennas about half way
between the floor and the ceiling or
at about 5 meters (16 ft. 8 in.) in
height.
• The recommended coaxial cable for connecting the
antennas to the tuner and antenna divider is a 5D-2V
(50 ohm or higher). You can also use a 5C-2V (75
ohm or higher).
Signal loss: 5D-2V
50 m : 12.5 dB
100 m : 25 dB
5C-2V
50 m : 13.5 dB
100 m : 27 dB
• The coaxial cable should be as short as possible. The
signal loss increases as the cable length increases,
which has a greater impact than the difference
between 50 ohms and 75 ohms.

Mount the antennas as far as
possible from electric equipment
(e.g., elevators, computers, etc.) to
prevent radio wave interference.
