Chapter 1: Overview

In the case of SSB radios, the distance should be increased to
2 m (7 ft).
•
More than 2 m (7 ft) from the path of a radar beam. A radar
beam can normally be assumed to spread 20 degrees above
and below the radiating element.
•
The equipment is supplied from a separate battery from that used
for engine start. Voltage drops below 10 V (20 V for 10 kW open
array scanners) in the power supply to our products, and starter
motor transients, can cause the equipment to reset. This will not
damage the equipment, but may cause the loss of some informa-
tion and may change the operating mode.
•
Raytheon specified cables are used at all times. Cutting and
rejoining these cables can compromise EMC performance and so
must be avoided unless doing so is detailed in the installation
manual.
•
If a suppression ferrite is attached to a cable, this ferrite should not
be removed. If the ferrite needs to be removed during installation
it must be reassembled in the same position. Section 2.1 Installing
the Radome Scanner includes instructions on fitting a ferrite.
The following illustration shows a typical range of suppression
ferrites fitted to Raytheon equipment.
Connections to Other Equipment
If your Raytheon equipment is to be connected to other equipment
using a cable not supplied by Raytheon, a suppression ferrite MUST
always be fitted to the cable close to the Raytheon unit.
