ALFA Network ARS-915PR in an indoor omni-directional RP-SMA male 915 MHz dipole antenna with 2 dBi gain. The antenna is 7.7 inches tall and has a 90 degree elbow. Suitable applications are as a factory replacement antenna for Helium miners and other IoT hardware. This antenna can be paired with this compatible magnet base

Get the right connection:

RP-SMA Male (this model): inside threading, center hole
SMA Male (other model ARS-915P): inside threading, center pin

SMA is more commonly used in 915 Mhz radios such as LILYGO Meshtastic radios, while RP-SMA is more common in WiFi. However both connection types can be used in either technology, so be sure to check your connections.

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 only).

Beware 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. Why buy a 5 dBi when you can get a similar looking "18 dBi" for the same price, right? Rokland has been making antennas for over 14 years for WiFi, 4G, and other applications. Our 915 MHz antenna are listed with actual specifications. You also do not want extremely high gain as your path will be very narrow and miss other hotspots.

I see similar looking antennas online that say for 600 MHz to 2700 MHz, is a wider frequency spectrum better? 

Antennas with a focused spectrum will have better performance on that band segment vs antennas with 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 900-930 MHz to give you maximum performance.
