Omnidirectional antenna is for 868 Mhz LoRa/LoRaWAN antenna center tuned to 868 Mhz. It is compatible with any LoRa device, RAK, Bobcat, Syncrob.it and Nebra Hotspot Miners to mine Helium (HNT) crypto. It stands at 16inch tall. It is also an Outdoor Rated fiberglass Omnidirectional stick antenna that offers 5dBi gain in the 900-930 MHz ISM band. The unit is ultra-rugged and ly suited for 900 MHz for point-to-point / Machine to Machine communications.Our 5dBi 868 Mhz low profile 16inch fiberglass antenna with N-male connector including an RP-SMA male to N-female coaxial cable and U-bolt bracket mount. certified and designed for outdoor environments and is weatherproof. it has better wind resistance due to its smaller surface area. compatible with the RAK V2, Bobcat 300, Nebra Indoor/Outdoor, SenseCAP M1, SyncroB.it, Helium Hotspot, Kerlink AP but requires an RP-SMA male to N-female coaxial cable to fit, and we carry compatible coaxial cables.
