2.8 Communications Antenna Installation Notes
For best results while in Split Mode, it is recommended that the one VHF communications antenna is l o-
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 ai r-
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-MP3 in Split
Mode.
