Antenna Connector types [SMA vs RP-SMA]

In general, Helium Hotspots ship with RP-SMA connectors.

However, if you purchased one of the first 700 Helium Hotspots, it shipped with a regular SMA connector.

If you want to upgrade your antenna, double-check your configuration (use the example pictures below), to make the decision for which connectors to buy.

You can also pick up SMA or SMA-RP pigtails for a few bucks.

IMHO the existence of RP-SMA was a total dud, the industry somehow believed that something as simple as a pigtail won’t ever exist and hence defeat the purpose of stopping one from connecting a high gain SMA antenna into a consumer wanna be low power RP-SMA device…
