10PCS 100mm 2.4G Receiver Antenna for Frsky X4R X4RSB XM XM+ R-XSR Replacement Antenna IPEX 4 V4 Port S6R S8R F30 F3OP F40 F4OP

Using this one the Jumper ELRS receiver after the original dipole antenna was lost in a crash. This one has the smaller UFL connector it needs. No loss in range that I can tell, I’d recommend

Works great with xsr and xm+

I’m sure these work great for what they are designed for. I just want to put in here that these will not work on your Moblite 7.

Perfect fit

The active element is supposed to be 23..5mmm or about 0.92 inches. These have an active element of 1.1 inches or nearly 28mm. At least they're too long instead of too short. You can just cut them down to the correct length. If you have signal trouble, check the length of the active element, which is the exposed wire after the black insulation. If it's not measuring 23.5mm, that's probably why. I just cut it down and test flew my quad. I had good signal.

Got these for replacement on an XM+ RX, as the stock ones broke where the wire meets the connector, causing a failsafe from approx 100' onto concrete, destroying 3 motors, and a RunCam split micro camera. These have heat shrink from the connector down the wire for stress relief. Nice touch.

Got these for xm + and my rxsr....they can pop off kinda easily so I always use a dab of hot glue over the connection point n it works as one would think but I think the exposed part of antenna is wrong length after trying a different length that I saw on some YouTube channels that seems to work better for me atleast

I build race drones, worked perfect for my FRSKY r-xsr.The snap fit is tight and quality of the antenna is good range is as expected.A bit pricey for just 10wires.
