Lemon Rx DSMX Compatible Diversity Satellite Receiver (LM0037)

Lots of people use Spektrum Radios, but the Spektrum range of drone compatible receivers is currently pretty limited. A good alternative is Lemon Rx. Unlike lots of other Spektrum compatible receivers, the Lemon Rx products aren’t inferior in terms of performance or reliability, nor are they Spektrum clones. Best still they are much better value than the Spektrum products!

This particular Rx, is a DSMX satellite receiver which is compatible with DSMX Spektrum and DSMX Orange Rx products. It is also backward compatible with DSM2 modulation but must be used with a DSMX compatible primary receiver. As a Satellite RX you can use it in conjunction with a full size receiver for a really secure connection. Equally, it is a full range receiver with diversity on its own, so you can connect it directly to a compatible flight controller i.e. a Naze32 or SP Evo for a really neat solution.

Weighing only 2.7g with the case this receiver is incredibly lightweight and with a 22x19x7mm footprint this receiver can fit in some tight spots! If you use a spektrum transmitter you simply cannot beat the LemonRx receivers for size, price, and performance.

To bind this satellite receiver with your radio, you will need to use either a full size receiver or CLI commands with flight controller.

Features:

• Spektrum DSMX compatible satellite full range receiver
• True diversity dual antennas with independent processor for monitoring singal on both antennas
• Antennas extended for carbon fuselage / metalic structure installation

How dual antennas work

An independent processor monitors an incoming signal and choose the appropriate antenna for reception. This allows 2 different location for installing the antennas along with different orientation. Satellite is no longer needed for receiver diversity. This greatly reduces weight with increased overall reliability in comparison to the use of a primary receiver with satellite receiver.
