2. Installation procedure

1) Precautions for transporting and storing the antenna
• An antenna is a heavy load. Be very careful about handling it.
• Do not allow the antenna fall on its side while it is stored or being installed.
• Do not apply rope to the antenna in the way that squeezes or deforms the
radiating section.
• When hoisting the antenna by a crane, do not hoist it by attaching a belt or
a rope only to the antenna's radiating section as shown in Fig.2-1.
• When lifting the antenna(Fig.2-2):
Wrap a cloth around the antenna's support section located at the bottom of
the radiator, and then attach a belt to it to lift the antenna.
2) Installation procedures
a) Maintain a flat level surface on which to install the antenna.

Fig.2-2 Lifting the Antenna
• Use sufficiently thick steel material and reinforcement material for the
antenna's installation surface (mount base) to reduce vibration and
impact. Keep the mount base flat and smooth.
• If there is a partial gap between the mount base and the antenna
chassis's legs, work on the installation surface so that it becomes flat
and smooth. If a gap exists and the antenna is tightly clamped, the
chassis will distort and become damaged by vibration.
