I have one of these:
It's a 4G LTE Bell turbo hub, for providing 4G Internet in rural areas.
I'm not getting very good cellular signal strength for the 4G/LTE connection, so the Internet is pretty poor. The device reports that the cellular internet connection is around -87DB, and it really should be better than -70DB for optimal performance.
The manual says I can attach 2x external antenna to the antenna ports on the back of the device, which will help boost the strength of the 4G/LTE connection
So I'm trying to find an appropriate 4G/LTE external antenna I can use on this hub.
Note: This is NOT the Wifi signal strength, this is for the cellular 4G/LTE Internet connection to Bell's cell towers.
Here's the user guide for the device, it discusses using an external antenna on page 12:
The problem is that the connectors for the antenna look a little weird - it's different from a typical wireless router which has a threaded connector with a pin in the middle. This connecter does not have a pin, instead it has a receptacle, so all of the high gain wifi antennas I have floating around won't work.
This leads me to believe that it needs a specific kind of 4G/LTE antenna, not just any old 802.11 wireless antenna.
See this picture of the connector:
What's the best antenna to get?
