RC radio receiver card backside connectors (optional)
RC radio receiver card can handle two independent radio channels. Channel “A” is
usually supplied with built in radio (or external radio for special request). Channel “B”
only can be used with an external radio unit. If the channel “A” is supplied with built in
radio (RTX 2U2), only the antenna should be connected to “ANT” connector. Pay
attention for using UHF antenna with suitable end of line resistor (50 ohm), and the RF
cabling should have minimal loss.
Note:
If you want to use channel “B” with external radio unit, please contact your
distributor.
