nidici FOXEER Lollipop-3 5.8GHz Stubby Antenna RHCP 2.5Dbi FPV Antenna SMA Male for FPV Racing Drone Fatshark Goggles TX RX (Pack of 2)

I very much like the style and low profile design of these antennas. However, I measured both of my antennas on a calibrated network analyzer (one that costs about as much as some houses..) and I found the performance to be not very good. They certainly do not meet the specifications in the listing. The tuned center frequency is low at about 5.4 GHz. At around 5.8 GHz, where they are supposed to be tuned, the return loss was 5.7 dB (VSWR 3.16:1). Keep in mind that a 5.7 dB return loss means 27% of the power would be reflected back IN to the transmitter. I would be OK using these antennas in a receiver, but not on any higher power VTX. On a side note I also measured a pagoda style Foxeer antenna I purchased on Amazon, and it was properly tuned with great return loss performance, so not sure why the tuning on these were so off.

These rock. No more worrying about crashing and breaking a long antenna. Just a clean little nub that broadcasts and reduces exceptionally. Love the color too.

shipped fast and works great
