Helium Miners - Frequency Bands and Antenna Connector Types.

Helium has approved a number of third-party manufactured hotspots which are primarily available in the US and Europe, operating in the 915 and 868 MHz frequency bands. Many of the miners are able to operate in either frequency band, but certain units are only available for a single frequency band. The antenna connectors used typically RP-SMA for indoor Helium miners and Type N connector (male & female) for outdoor gateways.

An external LoRa antenna can be connected via an accessible RP-SMA female connector. This is the single point of connection for an antenna. The Nebra miners operate on a single frequency band. They are available at either 915, 868 or 470 MHz.

Nebra HNT Outdoor Hotspot Miner (915 MHz - US / 868 MHz - EU / 470 MHz CN)  

The Nebra HNT Indoor Hotspot Miner is a Helium Network-compatible miner which can be used to mine HNT and validate other Helium Network gateways. It also has EthernetBluetooth, and WiFi connectivity. 

The gateway is housed in a rugged IP67 enclosure. It carries external WiFi and LoRa N-type female connectors. It is supplied with a 3 dBi external fiberglass LoRa antenna and a WiFi antenna. The Nebra miners operate on a single frequency band. They are available in 915, 868 or 470 MHz versions.

Syncrobit SP Helium HNT miner (915/868 MHz - US/EU)

The Syncrobit SP Helium miner is a Helium network Gateway that is LonFi enabled. It delivers extremely low-power, but efficient performance. The Syncrobit HNT miner carries a female RP-SMA connector for attachment of the LoRaWAN antenna supplied with the unit. Synchrobit supplies a 5.8 dBi and 8 dBi antenna for this unit.  The antennas are N connector antennas and are supplied with a Type N female to male RP-SMA antenna cable. It also includes an outdoor enclosure. 

The Linxdot Helium hotspot (915/868 MHz - US/EU)

The Linxdot Helium miner is an indoor HNT miner that comes in ABS plastic housing. It is quick and easy to set up via smartphone apps. It has BluetoothWiFiGPS, and Ethernet connectivity as well as an onboard LoRa concentrator. The power supply is 12V DC.

This miner comes with a 3dBi LoRa antenna which is attached via an RP-SMA female connector. It has dual frequency operation and can be used in Europe and the US.  

It uses Raspberry Pi 4 and it's firmware can be updated via smartphone.

ClodPi Pro hotspot (IN 865 MHz)

The ClodPi Pro hotspot is a Helium-approved miner designed for the Indian market. It operates in the 865 MHz frequency band and has Ethernet and WiFi connectivity in addition to its LoRa concentrator.
