Antenna polarization

For optimum RF link performance, mount the antennas in an orientation

that allows for the best possible signal reception when the helicopter is in

all possible attitudes and positions. Orient the internal receiver antennas

perpendicular to each other (see Receiver Installation).
When using a DSMX remote receiver—Use double-sided foam tape to

mount the remote receiver so that the antenna is perpendicular to the longer

main receiver antenna. The remote receiver antenna must be at least 2 inches

away from the main receiver’s antenna. The AR7200BX is compatible with all

DSM2 and DSMX transmitters, even when using the optional DSMX remote

receiver.
