2.9 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 should be accomplished in accordance with AC 43.13-2B, and /or aircraft manufacturers’
recommendations.
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 PAC15EX in Split Mode.
