Nelawya 868MHz LoRa Antenna Omni-Directional 3dbi Gain SMA Male LoraWan Antenna for Meshtastic LoRA ESP32 LoRa OLED Board + 15cm IPEX Extension Cable 2 Pcs

Resonates very close to 868MHz, unlike many antennas sold for this frequency. The SWR is around 1.2:1 on both my examples which is not bad though not as good as the equivalent Paradar antenna. The Paradar is significantly more expensive though.

You get what you pay for, and these are definitely worth £10 for a pair.Normally when you buy cheap 868 antennas they're actually 915MHz antennas and someone has said "close enough". The pair of Nelawya antennas I received are much closer to 868. For that reason alone these are 100x better than other cheap ones. The SWR comes in at about 1.7, which is good, but not great.They're actually very good at around 890MHz (1.2 SWR). If they could have just shifted slightly closer to the stated frequency these would be worth 5*

Used for a repair or a Davis weather station where the antenna failed, made a mount for it and does the job well and improved reception

These twin antennas are very well made and excellent value for money.As soon as I received them my son tested them on a VNA analyser. In the vertical position they scored 1 which is near perfect but horizontally they scored a poor 3, I shall be using them vertically.I don’t normally expect something this cheap to be this good but they are.
