2.7 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 antenna

relocation must be accomplished in accordance with AC 43.13-2A, aircraft manufacturers’ recommenda-

tions 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 PMA8000-SR in Split Mode.

2.7.1 Audio Active Output

Pin 24 on the J1 connector (and PA Mute Pin 12 on J2) should be connected to Apollo CNX80 for audio

message prioritization, refer to CNX80 installation manual for details.
