The arrows on some radar altimeters are a reference reminder that the antennas must be mounted on the same longitudinal axis on the aircraft. Normally, the antennas are mounted so that the arrow head of one antenna points to the tail of the other antenna arrow. The 2 arrows can point at each other as long as they are on the same longitudinal axis. Click here to view a basic diagram of proper radar altimeter antenna installation.
