2.7. Antenna Installation
The transceiver requires a standard 50 Ω vertically polarized VHF antenna. Follow manufacturer's
instructions for antenna installation. In addition, consider the following recommendations:
• The COM antenna shall be on an electrical conductive surface or, on a ground plane with
sufficient area of approximately 60 x 60 cm installed. (VSWR ≤ 3:1)
• Separate the COM antenna from any installed GPS antennas by at least 50 cm and as far
away from any ELT antenna.
Note: Some ELTs have exhibited re-radiation problems generating harmonics that may cause
interference with other receivers like GPS. This can happen when the transceiver or other COMM
devices are transmitting on certain frequencies such as 121.5 MHz or 121.175 MHz, which may
cause the ELT output circuit to auto-oscillate.
2.8. Configuration Setup
The configuration setup enables the avionics technician to set up the equipment configuration on
ground.
We do not recommend performing changes on the configuration setup in-flight.
In most cases, entering configuration setup will be from the primary controller to access controller and
transceiver parameters. If installed, the second controller (RCU6201) should be switched off.
Configuration setup on RCU6201 gives access to parameters of second controller. RCU6201
configuration setup shall be used only if different settings for "BRIGHTENSS" or "ILLUMINATION
CURVE" are required.
Note:
• For single block AR620X, primary controller is this one directly connected to transceiver,
for remote RT6201 transceiver primary controller is this one connected to primary control
interface.
• After power on the second controller (RCU6201) parameters are synchronized with those
stored in primary controller. Any stored parameters in second controller (RCU6201) will be
overwritten!
