2.6 Marker Antenna Installation
Refer to aircraft and antenna manufacturer's installation instructions, as well as AC43.13-2B (or later
revision), Chapter 3, for information on proper antenna installation techniques. The marker beacon an-
tenna must be mounted on the bottom of the aircraft.
2.7 Communications Antenna Installation Notes
For best results while in Split Mode, it is suggested that the one VHF communications antenna be located
on top of the aircraft while the other communications antenna be on the bottom. Any antenna relocation
must be accomplished in accordance with AC 43.13-2B, aircraft manufacturers’ recommendations 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 En-
gineering makes no expressed or implied warranties regarding the suitability of the PMA6000B
in Split Mode.
2.8 Unit Installation
To install the PMA6000B, gently slide the unit into the mounting rack until the hold-down screw is en-
gaged. While applying gentle pressure to the face of the unit, tighten the 3/32" hex-head screw next to the
copilot control shaft until the unit is secure. DO NOT OVER TIGHTEN.

Internal damage will result.
2.9 Post Installation Checkout
2.9.1 Required Test Equipment
In order to return an aircraft to service after installation of the PMA6000B with marker beacon receiver,
the installer must have access to a Marker Beacon signal generator:
a. IFR NAV401L, NAV402AP, IFR4000
b. TIC T-30D, T-36C
Equivalent test equipment is acceptable as long as the testing requirements can be met.
2.9.2 Power Test
After wiring is complete, verify power is ONLY on pin 43 of the connector, and airframe ground on con-
nector pin 29. Failure to do so will cause serious internal damage and void PS Engineering's warranty.
1. Apply power to the aircraft and avionics.
2. Plug headsets into the pilot, copilot, and occupied passenger positions.
3. Verify fail-safe operation by receiving and transmitting on com 1 from the pilot position, with the
audio panel power off.
4. Switch on the unit by pressing the volume (VOL) knob.
5. Check intercom operation.
6. Push the Com 1 Xmt select button (lower row).
