SIGNUX ANT03 LoRa
868 MHz gain, held on by a magnet
Omnidirectional magnetic-mount antenna for the 868 MHz ISM band used by LoRa and LoRaWAN equipment in Europe.
SX-ANT03-LORA adds 3 dBi of gain and, more to the point, it lets the antenna leave the enclosure: the radio stays inside the cabinet and the antenna goes on top of it, where there is something to radiate against.
The base is a magnet. It holds on any steel surface — a cabinet roof, a pole bracket, a machine frame — with no drilling and no mounting kit, and it can be moved afterwards if the coverage turns out to be better a metre away. That steel surface is not only a support: it works as the ground plane the antenna needs, so the same antenna sitting on plastic radiates worse than on a metal lid.

What sets it apart
868 MHz, 3 dBi
Tuned for the ISM band that LoRa and LoRaWAN use in Europe, with vertical polarisation and 50 Ω.
Sticks to steel, no drilling
A magnetic base holds it on a cabinet roof, a pole bracket or a machine frame. No bracket to fit, and it can be moved if the coverage turns out to be better a metre away.
-40 to +80 °C, RoHS
Outdoor temperature range, the same for storage, and ten years of storage life.
