This is an outdoor fiberglass encased omni-directional 915 MHz antenna with 3 dBi gain, manufactured by RAK Wireless. Also included is an outdoor bracket designed for mounting to a pole or PVC pipe. THIS DOES NOT INCLUDE THE RAK MINER ITSELF.
This antenna is compatible with the RAK V2, Bobcat 300, Nebra Indoor, SenseCAP M1, Kerlink, Linxdot, SyncroB.it, Helium Hotspot, Kerlink, FreedomFi & LongAP, (915 MHz USA and Australia versions + Europe 868 MHz also) but requires an RP-SMA male to N-female coaxial cable to fit, and we carry compatible coaxial cables. This has the same gain as the Bobcat factory antenna and would be a better choice for RAK or Nebra owners.We do recommend RokTape to seal all outdoor connection points.

Be cautious of gain inflation- some places arbitrarily inflate antenna gain numbers to appear better than competing products. Because gain cannot be easily measured by the end users, we have seen similar antennas marketed as numbers like 18 dBi to 30 dBi that are not even 20 inches tall. Rokland has been making antennas for over 14 years for WiFi, 4G, and other applications. Our 915 MHz antennas are listed with actual specifications. You also do not want extremely high gain as your path will be very narrow and miss other hotspots.
Antennas with a focused spectrum will have better performance on that band segment vs antennas with a very wide spectrum. We would not recommend using antennas that are also WiFi 2.4 GHz compatible with your mining equipment. This antenna has a frequency range of just 860-960 MHz to give you maximum performance.
Need a low loss shielded cable?
This requires an RP-SMA male to N-female coaxial cable to fit your miner, and we carry compatible coaxial cables.
Use with your Helium miner to help increase your coverage area. This antenna can be used outdoors and is weather and dust-proof.
