915MHz LoRa Antenna Omni 5dbi Gain SMA Male Connector 2 PCS

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

Fast shipping.

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 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 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.

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

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 <= 1.7 over a span of approximately 25 MHz.

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.
