2.8 Communications Antenna Installation Notes
For best results while in Split Mode, it is recommended that the one VHF communications antenna is lo-
cated on top of the aircraft while the other communications antenna is installed on the bottom. Any an-
tenna relocation must be accomplished in accordance with AC 43.13-2A, aircraft manufacturers’ recom-
mendations and FAA-approved technical data.
WARNING
It is probable that radio interference will occur in the split mode when the frequencies of the two air-
craft radios are adjacent, and/or the antennas are physically close together. PS Engineering makes
no expressed or implied warranties regarding the suitability of the PMA8000B in Split Mode.
2.8.1 Audio Active Output
Pin 24 on the J1 connector (and PA Mute Pin 12 on J2) should be connected to Apollo CNX80 for audio
