• 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 scanner height and installation location,
take into consideration the reduction of vibration, the strength of the hull and
the scanner mount base, and maintenance properties.
• Provide for maintenance space: platform, safety link, hand rail, steps, etc.
