
Antenna is the precise material, so be careful not to make damage or form
change.

When moving antenna, use the tool suitable to rating. In addition, use the rated
carrying device which is at least 200 % or more than antenna considering the
stability.

Be careful not to give too much strength to the antenna.

If it rains, suspend connecting the feeder cable and antenna.

Fix it after adjusting the direction of antenna exactly.

Distance between steel tower and antenna and the distance between send-
receive antennas are based on the antenna layout.

Attach the antenna on the position specified in the drawing.

Install the antenna not to make a feature change of the antenna considering the
direction of the radiation

Connect the antenna not making the alien substance flowed so that Passive
Inter-Modulation Distortion (PMID) is not affected.

Measure VSWR of all antennas and the value should be within the regulated
value.
When you install the antenna, the antenna must be within the protective angle
(left/right side 45° each from the central axis) to prevent the antenna from
lightning damage.
