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 aircraft
radios are adjacent, and/or the antennas are physically close together. PS Engineering makes no ex-
pressed or implied warranties regarding the suitability of the PMA7000M-S in Split Mode.
2.8 Wireless telecommunications interface
The PMA7000M-S has interface capability with units such as the AirCell AGT.01. It is the user’s responsi-
bility to determine the appropriate legal use of the equiment, and provide the services.
Interface to the AirCell, or any telecommunications device, is through the J1 (bottom) connector, pins 14
and N. Pin 14, labeled cellphone ring, is connected to pin V of the AirCell connector and pin N of J1 is
connected to pin W. The shield is terminated to pin K on the AirCell. On the AirCell interface these are
listed as data/fax lines, but they are used for voice interface in this case.
Use a 2-conductor with shield cable, and connect the shield to Pin K of the AirCell.
If interface is desired with another type of wireless telecommunications unit, the aircraft owner can pur-
chase an after-market interface cable. By Federal Communications Commission (FCC) regulations, these
can only be used on the ground in the United States.
PS Engineering makes no expressed or implied warranty that the equipment will be compatible with any
devices other than AirCell.
Some interface cables are available from MobileQuest at 800-882-1288, or (215) 734-7000. The following
