Table 3-5 lists non-Garmin antennas currently supported by the GDL 5X/5XR. For non-Garmin antennas,
follow the manufacturer’s installation instructions. It is the installer’s responsibility to ensure that their
choice of antenna meets FAA standards according to the specific installation.
Table 3-4 XM Satellite Radio Antenna Minimum Requirements
Characteristics Specifications
Frequency Range 2332.5 to 2345 MHz
Gain (Typical) 24 dB*
Noise Figure <1.2 dB
Nominal Output Impedance 50 Ω
Supply Voltage 3.6 to 5.5 VDC
Supply Current (maximum) 150 mA
Operating Temperature Gain -40 to +85° C
*For each 1 dB gain over 24 dB, add 1 dB of attenuation into the antenna cable path between the
antenna and the GDL 51R/52R. Note that gain specifications are defined at the output of connector for
some antennas, e.g. GA 24 TNC. Additional attenuation will be required for any modifications made to
the cabling to these external antennas.
