PS Engineering PMA7000B Series Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.5.1 Marker Antenna Installation A marker beacon antenna, appropriate to the type and speed of the aircraft, is required (not included). Refer to aircraft and antenna manufacturer's installation instructions, as well as AC43.13-2A (or later revision), Chapter 3, for information on proper antenna installation techniques. The marker beacon antenna must be mounted on the bottom of the aircraft. 2.5.
PS Engineering PMA7000B Series Audio Selector Panel and Intercom System Installation and Operator’s Manual 2.7 Communications Antenna Installation Notes For best results while in Split Mode, it is recommended that the one VHF communications antenna is located 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’ recommendations and FAA-approved technical data.

This section is divided into four sections covering the basic operating areas of the PMA7000B systems.
PS Engineering PMA7000B Audio Selector Panel and Intercom System Installation and Operator’s Manual When switching from COM 1 to COM 2 while Com 2 has NOT been selected, Com 1 audio will be switched off. In essence, switching the mic selector will not effect the selection of Com receiver audio. When the duplex enable, or TELEPHONE mode is implemented during installation, Com 3 becomes the “TEL” position.
PS Engineering PMA7000B Audio Selector Panel and Intercom System Installation and Operator’s Manual Note: Due to the nature of VHF communications signals, and the size constraints in general aviation aircraft, it is probable that there will be some bleed-over in the Split mode, particularly on adjacent frequencies. PS Engineering makes no warranty about the suitability of Split Mode in all aircraft conditions. Note: Split Mode does not turn off other (Nav, ADF, etc.) selected audio to pilot.
