The antenna of the Sanwa RX-481 receiver is already integrated into the housing. So, there’s no more antenna cable that has to be fixed on the chassis. Therefore, the antenna cable can’t be broken or disconnected anymore when it comes to a crash.
The integration of the antenna into the housing doesn’t have any negative influence on the range and interference-free transmission. The Sanwa RX-481 receiver has 4 channels and can be operated in FH-3 or FH-4 mode.
Compatible to all Sanwa transmitters, that can be operated in FH3/FH4 mode, e.g. M12, M12S, MT-4, MT-4S.
