2.8 Communications Antenna Installation Notes
For best results while in Split Mode, it is recommended that the one VHF communications antenna is locat-
ed 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 43.13-2B, 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 PMA450 in Split Mode.
