The EX500/EX600 can operate with both Datalink systems simultaneously. With both 2-Way Datalink

and Broadcast Datalink systems installed, the MFD can provide Avidyne's unique MultiLink features,

which include text messaging, flight tracking, and enhanced weather coverage.

4.8.1 ORBCOMM Antenna Details (EX500 Release 4.0 and earlier only)

To improve ORBCOMM reception performance and minimize potential damage to the ORBCOMM

transceiver, an antenna design with a DC-short between the antenna center conductor and shield

termination is required. The following commercially available antennas are acceptable:

➥ Refer to manufacturers for detailed performance specifications and aircraft applicability

● Mount the ORBCOMM antenna on the aircraft top-side, as high on the fuselage as practical.

● Mount the antenna no closer than 36 inches to other transmitters. You may need to relocate other,

less location-sensitive transmitters, to achieve optimal datalink performance.

● On radar-equipped aircraft, mount the antenna as far aft as possible, but no closer than 36 inches

from vertical obstructions (such as the vertical stabilizer). Reflected radar energy may cause

damage to the datalink transceiver.

Install the radar in accordance with the applicable portions of AC 43.13 and the antenna

manufacturer’s instructions. For more information, see Figure 33, “Installing the 2-Way Datalink

Antenna,” on page 94.

4.8.2 Broadcast Antenna Details

● Mount the antenna no closer than 36 inches to VHF-Comm transmitters of 15 Watts or less. For

more powerful transmitting antennas, ensure a minimum separation of 48 inches.

● If you are installing an XM/VHF-Comm combo antenna to replace an existing approved antenna

installation, the existing separations are acceptable. SATCOM antennas transmit at 40 Watts and

should be separated by the largest distance possible. This distance must be a minimum of 36

inches.

● When routing the broadcast antenna cable, try to achieve the maximum possible separation from

transmitter antenna feed cables, especially with SATCOM and other high power transmitters. VHF

transmitter antenna feed cables of 15 Watts or less require only a minimal separation.

● Receive-only antennas such as GPS and ADF do not produce interference and require little

separation. To allow for separation from transmitters, you can place the XM antenna as close as

possible to these types of antennas.

● For further details, including installation pre-testing, see the Broadcast Receiver’s installation

manual.
