This Omnidirectional antenna is for 900-930 Mhz LoRa/LoRaWAN antenna center tuned to 915 Mhz. It is compatible with any LoRa device, RAK, Bobcat, Syncrob.it and Nebra Hotspot Miners to mine Helium (HNT) crypto. It stands at 16" 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 perfectly suited for 900 MHz for point-to-point / Machine to Machine communications. | Our 5dBi 915 Mhz low profile 16" fiberglass antenna with N-female connector and U-bolt bracket mount. This is certified and designed for outdoor environments and is weatherproof. Plus it has better wind resistance due to its smaller surface area. | This is compatible with the RAK V2, Bobcat 300, Nebra Indoor/Outdoor, SenseCAP M1, SyncroB.it, Helium Hotspot, Kerlink & LongAP but requires an RP-SMA male to N-male coaxial cable to fit, and we carry compatible coaxial cables. It also works with other Helium hotspots but may need different cable connectors. | This antenna does ship with a cable. an N to RP-SMA interface extension cable to connect the antenna to an RP-SMA connector.19.5 inches length, RG316.RP-SMA male connector on one end and an N Male connector on the other end.Includes 2 U bolts and mounting bracket as pictured, plus antenna. This is NOT a WiFi antenna or 4G cellular antenna, it is ONLY for 915 Mhz sub 1 GHz HaLow or LoRa application, or other applications this band. | 35-degree vertical beamwidth, 360 degrees horizontal, N-female connector. VSWR ≤ 1.5 with 5 dBi gain, 50-ohm impedance, max input power 50W, made of Fiberglass, Copper, and Aluminum Alloy
