Tenmory 915MHz LoRa Gateway Antenna Omni 5dbi Gain RP-SMA Male Connector 2 PCS

Good quality !!

As advertised

Bought these to see if they were better than the original Lilygo antennas. Received signal strength for these was -120db, signal strength for originals is -70db. These are either not 915MHz or poor quality.

Per other reviewers, of an almost copy of this antenna (except pin reversed). I found almost perfect performance on my nanoVNA in the straight position, but the match was very very poor at 915 Mhz in the folded configuration. Don't buy if you can't use it straight.

I bought 4 of these and tested them all with a nanoVNA. 2 of them had between 1.3-1.5 SWR at 915mhz but were most resonant around 928mhz. One was not well tuned and read 1.8 SWR, the other was perfectly tuned at 1.08 SWR. As soon as the antennae are bent 90°, the swr will range from 2.2-3.0. Works fine straight.
