A3.2.4 Mounting Antenna and Wiring
This section describes the mounting of the antenna to YFGW710 main body, the installation of
the external antenna, and their wiring.
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 un-
screwed cap should be stored in order to replace it immediately after the antenna or antenna
cables are removed.
NOTE
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.
