Chapter 1: Overview 3

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.
