The RT-7000 PMR/RMR operate in the aircraft environment. Each 7000 product uses a
standard +27.5 VDC input, features audio interfaces that are compatible with
standard aircraft audio panels, and mounting hardware that has been tested to meet
crash and safety standards of DO-160G (aircraft environmental standards similar to
MIL-STD-810).
The RT-7000 PMR/RMR however is just one part of a complete communications
system. Other components in the aircraft include an Audio Control Panel (ACP), 1 or
more antenna and antenna controllers, and optional Remote Control Display Unit can
be used to completed the communication system.
Additional components include Antenna Controllers as well as the Antennas
themselves. The Antennas are the main external interface for the RF signals to
propagate to/from the aircraft. Antenna Tuning Converters are used when a “tunable
antenna” is utilized. Tunable antennas utilize embedded electronics to enhance the
performance of the RF signaling, hence making signals travel further or receive low
power signals (i.e. greater distances) by changing the RF characteristics of the
antenna depending on the channel of the RT-7000.
A 118 MHz High Pass Filter (HPF) is provided for installations that will be using the
Cobham Wideband Transciever (CWT) as a VHF ATC COM radio. The 118 MHz HPF is
a mandatory component for installations that need an RT-7000 radio system that has
been certified to TSO-C169a. Failure to install the filter could result in the radio users
experiencing interference in their received audio when flying close to commercial FM
broadcast radio transmit towers.
These commodities, technology or software are controlled in accordance with the United States Export Administration Regulations, Export Classification
