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

quality on these feels really great - they seem super sturdy and well-made, which is awesome for the price. The only bummer is that the fit wasn't quite what I was expecting, since I accidentally ordered the wrong size.

Works great with xsr and xm+

Used these on my FRSKY Receivers and they work like a charm.

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.

It works okay

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.

Works like new and secure fit

A bit hard to press on but that’s OK because they’ll also be unlikely to pop off accidentally.
