Adapters & Connectors

Start a Wireless Network

Connectors are a major source of confusion.

RP-SMA Connectors

Reverse polarity SMA (RP-SMA) is a variation of the SMA connector specification which reverses the gender of the interface


If you are installing an outdoor antenna you may want to consider a high quality low-loss cable and connectors spanning between the miner and antenna.

SMA connector

SMA connectors are semi-precision coaxial RF connectors as a minimal connector interface for coaxial cable with a screw-type coupling mechanism.
What kind of bracket do you use for an antenna?

What kind of adapter do you use for your miner?

This RF adapter converts a RP-SMA male connector to a SMA Female connector. Suits for WIFI devices and application.

Beware this adapter is a Reverse SMA (RP). It is mainly used in WIFI connections.

Also compatible with hotspot hardware for Helium network such Nebra Indoor, Bobcat Miner 300 and RAK Hotspot Miner V2.


The LoRaWAN™ protocol is a global standard that offers a long range (up to 15km) bi-directional communications with very low power consumption, allowing operation for up to ten years on the same battery.

A bigger antenna doesn’t necessarily mean wider/further coverage or more HNT earnings

A bigger antenna doesn’t necessarily mean wider/further coverage or more HNT earnings. Take a look at the images above and notice the different coverage for antennas. The higher dBi antenna is,
