Selecting The Installation Position - JRC JMA-5312-6/6HS Installation Manual

2.1
SELECTING THE INSTALLATION
POSITION
1) Physical selection criteria
• Install the antenna at the center of the mast on the keel line.
• If the antenna cannot be installed at the above position for some reason, the amount of
deviation must be minimized. And, reinforce the mount base and the platform and take
precautions to protect the antenna from vibration and impact at the installation position.
• To avoid the radiating section coming in contact with other installed objects while it is
rotating, ensure that there is at least 200 millimeters from the swing circle (turning radius) to
other installed objects (Fig.1). The swing circle of the JMA-5300MK2 radar's antenna is as
shown in Table 1.
