Receiver Upgrade on the Shuriken 180 Pro

Lemon Rx DSMX-Compatible Diversity Satellite Receiver

Unfortunately the stock HolyBro DSMX-compatible receiver quit working in my Shuriken 180 Pro with not many flights on it. Since it had a single receiving antenna, I took this opportunity to upgrade to a dual antenna diversity receiver. The diversity receiver that I went with was the Lemon Rx LM0037 DSMX-Compatible Diversity Satellite. Lemon Rx’s description also explains the benefits of diversity: “True diversity dual antennas with independent processor for monitoring signal on both antennas.” Basically the receiver uses the signal from whichever antenna is receiving the strongest signal.

Since I had the Shuriken 180 Pro apart, I took this opportunity to also install HolyBro Micro minimOSD for the FPV camera. The photo below shows the HolyBro OSD unit and Lemon Rx Diversity Satellite Receiver temporarily connected to make sure all was operational before installing permanently.

Both the stock HolyBro receiver and Lemon Rx receiver are 3.3V and have standard satellite receiver connectors. The 3-wire cable that came with the Lemon Rx receiver was 20cm long so I cut it down to about 3.5cm, soldered the wires back together and covered the joints with heat-shrink tubing. I could have just as easily desoldered the connector from the Lemon Rx receiver and solder on the HolyBro pigtail. The Lemon Rx antennas are just slightly longer than the original HolyBro receiver.

After binding to my transmitter and verifying that everything was working normally, I removed the original plastic case from the Lemon Rx Diversity Satellite Receiver and installed clear Polyolefin heat-shrink tubing. This will also help keep the antenna micro RF coax connectors secure.

I removed the factory double-sided foam tape that was underneath the original HolyBro receiver, cleaned the surface with 91% Isopropyl Alcohol, installed new 3M double-sided foam tape, and installed the Lemon Rx Diversity Satellite Receiver.

The photo below shows how the original HolyBro receiver was oriented with the single antenna to one side. The original receiver was also in heat-shrink tubing but I removed it to see if I could find the cause of the failure.

Do the red tubes in the photo below look familiar? They are cut-down pieces of spray nozzles from a can of WD-40 or spray cleaner. The inside diameter was perfect for the Lemon Rx antennas and the outside diameter fits snugly in the antenna exit holes in the plastic frame spacer. I put a drop of CA glue on each to help keep them in place.

Where to Purchase Lemon Rx Receivers
The Lemon Rx LM0037 DSMX-Compatible Diversity Satellite Receiver was an outstanding upgrade to the Shuriken 180 Pro! Just the fact of having diversity antennas with a more capable RF reception is worth the price alone. You can purchase yours on the Lemon Rx website:
