SYSTEM DESCRIPTION AND INSTALLATION MANUAL

JetWave™ System

2 The areas which the risk exists are based upon the location of the antenna. This

means personnel operating on the apron, transient personnel, and the general

population in the controlled exposure category will not be exposed to levels in

excess of the limits. Maintenance personnel working close to the tail must be

protected by disabling the transmitter before they approach that area of the aircraft.

3 The JetWave™ system incorporates three fail-safe features to limit the potential for

human exposure to non-ionizing radiation:

a The system will not transmit unless the receiver is receiving a valid signal,

therefore if the received signal were to become blocked the transmitter would be

disabled.

b The antenna subsystem includes a hardware end-stop that prevents the

antenna pointing more than 2 degrees below the horizontal.

(7) An input into the JetWave™ system wired on the aircr

aft to a switch in the aircraft, to disable

the RF transmission. This switch would be used to prevent any radiation from the antenna in

the event of aircraft operations in the vicinity of the antenna, for instance when de-icing the

aircraft. This would be achieved by a defined procedure on the aircraft.

4.8 Tail Mount Antenna (If applicable)

A. Introduction

The TMA assembly is intended to be installed on the airc

raft tail tip/empennage. For the JetWave™

system to correctly point the antenna, the installation offsets should not exceed more than 1° off

heading, pitch or roll with respect to principal axis of aircraft. Depending on the airframe, the LRUs

and assemblies that follow would be installed outside aircraft fuselage as part of tail mount OAE:

• The TMA assembly

• KRFU LRU

• Radome assembly

• Radome fairing (if required).

• RF interconnect components:

• Tx waveguide

•Rx coax

• Rx coax to waveguide adapter

•O-rings

• waveguide and adapter attachment fasteners

The exact install location of the TMA assembly

and KRFU is a

irframe specific.

The radome, radome fairing (if required), and TMA/KRFU to aircraft interface brackets are airframe

specific; the related details are not covered in this manual.

The following factors must be considered when deciding where to install the antenna:
