4. Insert the cable into the connector – the centre contact should click into place in the body, the in-
ner shield should be inside the body of the connector and the outer shield should be outside the
body.
5. Crimp the outer sleeve over the shield.
6. Slide heat shrink tubing forward (flush to connector) and heat to shrink the tubing.
2.5.5 VHF Communications Antenna Installation
The antenna should be installed according to the manufacturer’s instructions. The following considera-
tions should be taken into account when locating the Antenna.
 The antenna should be well removed from any projections, the engine(s) and propeller(s). It
should also be well removed from landing gear doors, access doors or others openings which will
break the ground plane for the antenna.
 Avoid mounting the antenna within 2 feet of a GPS antenna, and as far as practical from any
ELT antenna.
 If the simultaneous use of two radio units is required then each antenna should be as far apart as
practicable for maximum isolation. We would recommend placing one antenna on top and one
on the bottom of the airframe. The Transmit Interlock function should also be used in this case
(section 5.6.8).
 Where practical, plan the antenna location to keep the cable lengths as short as possible and
avoid sharp bends in the cable to minimize the VSWR.
Electrical connection to the antenna should be protected to avoid loss of efficiency as a result of the pres-
ence of liquids or moisture. All antenna feeders shall be installed in such a way that a minimum of RF
energy is radiated inside the aircraft.
2.5.5.1 Antenna Ground Plane
When a conventional aircraft monopole antenna is used it relies on a ground plane for correct behavior.
For ideal performance the ground plane should be as large as practical; in any case at least one square
meter. In a metal skinned aircraft this is usually easy to accomplish, but is more difficult in a composite
or fabric skinned aircraft. In these cases a metallic ground plane should be fabricated and mounted under
the antenna.
The thickness of the material used to construct the ground plane is not critical, providing it is sufficiently
conductive. A variety of proprietary mesh and grid solutions are available. Refer to Advisory Circular
AC43.13-2B, Chapter 3.
2.6 TELEPHONE (Duplex) Function for Bluetooth ® capable Cell Phones
The TELEPHONE mode in the PAR200 is also compatible with cellular telephones with Bluetooth®.
hands-free headset interface. There is no wiring required, all functions are handled in the Bluetooth tele-
phone.
The PAR200 Bluetooth® interface is always “discoverable”, so you just need to search for the PAR200
from your Bluetooth-equipped phone or music source. The default access code is 0000, if needed. Once
the PAR200 has been “paired” with your Bluetooth device.
The telephone is distribution as dictated by the ISO, ALL, CREW.
ISO mode - only the Pilot is on the telephone.
CREW mode - only the Pilot and Copilot are on the telephone.
ALL mode - everyone is on the telephone.
