Installing the Polycarbonate Receiver Case (Optional)

1. Loosen the screws in the receiver case and remove the top.
2. Carefully remove the receiver board from the hard plastic case and

remove the protective film from the double-sided tape on the bottom of

the receiver.

Install the receiver board in the polycarbonate case by first inserting

antenna A into the cut out and antenna B into the cut out. Do not

allow the antennas to cross inside the case.

3. Press the case against the double-sided foam tape to secure the

receiver board.

4. Fold the case in the order shown and secure with double sided tape.

Feeder Antennas

The AR6260 incorporates two 7-inch feeder antennas, which are designed to be

easily mounted through the fuselage in carbon airplanes. Each feeder antenna

includes a coaxial portion (which can be thought of as an extension) and an

exposed 31mm tip antenna. The last 31mm is the active portion of the antenna.

Red LED Hold Indicator

The AR6260 features a red LED (labeled with H on the Polycarbonate Case) that

indicates the number of holds that have occurred since the receiver was last

powered on. The LED will flash the number of holds, then pause (e.g., flash, flash,

flash, pause, flash, flash, flash, pause indicates three holds occurred since the

receiver was last turned on). Note that holds are reset to zero when the receiver

is turned off. During the first flights of a new airplane, it’s recommended to check

the red LED hold indicator. If it’s flashing, it’s important to optimize the installation

(move or reposition antennas) until no hold occurs. On later flights, the LED Hold

Indicator can be used to confirm RF link performance.

Receiver Installation

Airplanes with significant carbon fiber construction can create an RF shielding

effect, reducing range. The AR6260 is designed to overcome these critical RF

issues in carbon airplanes by outfitting the aircraft with two external antennas at

specific points that will ensure secure RF coverage from all angles of the aircraft.
