■ Installation
1. Decide on a location for the antenna.
L The radiation direction is at right angles to the
antenna element.
2. Connect the coaxial cable to the antenna element.
L Wrap the antenna connector with the supplied
Rubber vulcanizing tape to prevent water seepage.
L Wrapping electrical tape (user supplied) over the
rubber vulcanizing tape improves water resistance.
3. Connect the support wire to the insulator at the
end of the antenna.
4. Attach the antenna onto the antenna mast with the
support wire.
5. Connect the support wire to the insulator at the
other end of the antenna.
6. Attach the antenna to the other antenna mast.
7. Stretch the antenna wires, as shown below.
Installation example:
Flat top:

■ Installation notes
NOTE: The supplied support wires are for mobile
operation only. Use durable wires for base station
purposes.
A dipole antenna emits RF signals at right angles
to the direction of the antenna element. Install
the antenna at the right angles of your target
communication direction.
Install the antenna as high and far away from other
structures as possible. For example, the antenna
height should be 10 m (32.8 ft) or more when using
a "flat top" installation, the lower side antenna height
should be 5 m (16.4 ft) or more when using an
"inverted V" installation.
The antenna must be at least 1 m (3.3 ft) away from
other structures.
Fine-tuning the antenna height, location, and so on is
necessary to obtain the best possible VSWR.
