Page 3: Selecting The Installation Position
7ZPRR0001 - Preface - This instruction manual describes installation method of the NTG-420 Transmitter-Receiver. This manual describes radar system configuration with X-band Radar Antenna and NCD-2247-1B PC type radar monitor display as an example. 1. Selecting the installation position 1) Physical selection criteria •... - Page 4 7ZPRR0001 • Avoid having a rope or signal flag from winding around the radiating section thereby preventing it from rotating. • Avoid the effects of dust and heat caused by smoke from a chimney. • When determining the appropriate antenna height and installation location, take into consideration the reduction of vibration, the strength of the hull and the antenna mount base, and maintenance properties.
- Page 5 7ZPRR0001 • If it is considered that sufficient installation height cannot be provided when the antenna is installed directly on the roof of the building, use a mounting rack or radar mast (Fig.1-3). Normally, when the antenna installation height is less than 2 meters from the roof of the building, provide a mounting rack assembled at an angle frame to install the antenna.
- Page 6 7ZPRR0001 • When installing two or more antennas, antennas in close proximity should have a minimum vertical elevation separation angle of 20 and a minimum vertical separation of 1m where possible, so that those antennas do not enter each other's vertical beam width range. 20°(min) Fig.1-5 Installing two or more antennas •...
- Page 7 7ZPRR0001 If the antenna vibrates a lot during test run, try to reduce or prevent vibration by reinforcing the antenna mount base or using wire stays attached to the radar mast. 4) Others • The design of the mounting platform for the antenna should take into account the vibration requirements defined by IEC 60945.

Page 8: Installation Procedure
7ZPRR0001 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. •... - Page 9 7ZPRR0001 b) Avoid using vibration-proof rubber and resin • Do not insert an elastic body, such as vibration-proof rubber or resin, between the mount base and the antenna chassis' legs. If rubber or resin is inserted, the amplitude of vibration increases, resulting in the possibility of damage to the antenna.
- Page 10 7ZPRR0001 Fig.2-3 Use of washer and corrosion-resistant measures d) Grounding and corrosion-resistant measures • Ground the antenna chassis and the installation surface (hull) by using an earth line. Apply sealant to the connection portion of the earth line to prevent corrosion and damage by vibration (Fig.2-4). Fig.2-4 Grounding and corrosion-resistant measures...
