2.8 Communications Antenna Installation Notes

For best results while in Split Mode, it is suggested 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.

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 expressed or implied warranties regarding the suitability of the

PMA7000M-S in Split Modes.

2.9 Post Installation Checkout

After wiring is complete, verify power is ONLY on pin 20 of the J1 (bottom connector) (dim

power may also be at Pin D and F), and airframe ground on bottom connector pin Z. Failure to

do so will cause serious internal damage and void PS Engineering's warranty.

2.10 Unit Installation

To install the PMA7000M-S, gently slide the unit into the mounting rack until the hold-down

screw is engaged. While applying gentle pressure to the face of the unit, tighten the 3/32" hex-

head in the canter of the unit until it is secure. DO NOT OVER TIGHTEN.
