5.5 Mounting Antenna and
Wiring
For Amplifier housing code 8 and 9, an antenna
is not attached to the transmitter. The following
provides the instructions for mounting the antenna
and installing the remote antenna and wiring using
antenna extension cable.
IMPORTANT
The antenna connector is covered with a cap
at the time of delivery. Keep the cap attached
until the installation of the antenna or antenna
cables to protect the inside connection part.
The unscrewed cap should be stored in order
to replace it immediately after the antenna or
antenna cables are removed.
CAUTION
To maintain the ultimate conditions of radio-
frequency signal, protect the connectors of
antenna, extension antenna cable, and arrester
from the corrosive atmosphere by the following
treatment.
1. Clean the connection to be protected.
2. Wind the butyl rubber self-bonding tape
around the connection. See the manual of
the tape about the winding.
3. To protect the butyl rubber self-bonding tape
from the environment such as ultraviolet rays
and so on, wind vinyl tape (or a vinyl type
self-bonding tape) on it.
5.5.1 Mounting the Antenna
Screw the provided antenna into the antenna
connector of the transmitter. The antenna may
be sold as available accessories and supplied
separately.
1. Unscrew the antenna connector cap on the
antenna connector.
2. Screw the provided antenna into the antenna
