This is not a 915 MHz antenna. Not good for LoRa radios. SWR at 915 MHz was 3.75:1. Best resonant frequency for this antenna is about 1.235 GHz where the SWR is 1.1:1. Not as advertised.

This antenna said it was for 915 Mhz, wrong its more like a 1Ghz and above. SWR is 4-5 at that frequency. Second one of the 2 in the pack is a SWR of 5+ at the 915MHz range. Do not buy if you want to increase range over the stock antenna.Picture shows this setup vs the stock little antenna which is matched quite well.

I have ordered a few of these antennas and all have been great. Every antenna has been checked on a my Nano VNA and have been near perfect at 906mHz. Using a RAK Wisblock and this antenna get more than 20 miles Line of sight. YMMV but for me the performance for value is pretty amazing. Make sure to have the shortest ipex to SMA cable possible!

I tested these on my NanoVNA, they get around 4 SWR from 900Mhz to 930 mhz. These are not for 915Mhz. total garbage. They get around 2 SWR at 850 Mhz. Likely a European antenna but 2 SWR isnt great to begin with

These antennas were NOT tuned for 915 MHz, the were tuned for 388 MHz, and are not suitable for the application that they were bought for. The product was mis-represented in the description as a product that is currently in high demand but that most users would be unable to verify.

I bought two batches in Jan and Feb 2024. The Jan batch has a good SWR of 1.34 at 908 mhz when it is straight; SWR of 2.7 when bent 90 degrees. The Feb batch has SWR of over 3 at 908 mhz when it is straight. The quality control of these antenna is questionable. If you buy, it has more to do with luck than with seller's misleading item description.

I order two set of two antennas for 915Mhz but after testing them I found that the SWR is very high on 915 MHz! Actually it’s over 4! (A good antenna should be at lower as possible, normally is supposed to be at 1,5 or less)So for sure I do not recommend this antenna since the performance is very bad and the SWR is so high that it can damage your transmitter!

Worked well for a pair of Heltec V3’s. Up to a mile NLOS, much more LOS.

I put 2 of these antennas on a vector analyzer and found they are both truly resonant at 915 MHz, just as advertised. A nice bonus is that they appear to be fairly broadbanded with SWR of

They're not perfectly tuned, one works best when folded 90deg with 1.25 SWR and 50 Ohm, the other works best when straight with 1.1SWR and 45 Ohm.So they're pretty good but you'll need some way to test them if you want to get the most out of them.

I ordered 5 sets of these for a LoRa MeshNetwork project. Very mixed results, some of them work great and seemed to dramatically increase the range I was able to get, others seemed to be no better than the 50¢ Chinesium rubber ducky the boards came with. I also noticed out of the ones that didn't have any noticable positive results that suddenly my SNR was tanking. Normally they sit around 10, in some cases using these antenna's I was seeing -18!!!! Great when you get a good one I suppose but kind of frustrated that over half of them have issues.

Purchased one set and was so pleased with the results, I bought another set. Tested them with a NanoVNA antenna tester and found they were all tuned correctly to the 915mhz frequency. These gave much better range for my Meshtastic T-Beams.
