Thingy91 GPS antenna recommendation?

[Allen]

Hello,

Is there any official recommendation for an external antenna, or other solution to getting better GPS performance?

Thanks

Hi Allen

Both the Siretta MIKE3A, the Maxtena MEA-GPS-S, and the Tallysman TW4020 should work as external antennas on the Thingy:91. Keep in mind that you'll need an adapter (like the MXHS83QE3000) from the connector on the board to the antenna itself.

Best regards,

Simon

EDIT: As suggested, here is a clarification on the statement above. All antennas mentioned above are active antennas and will need an adapter cable and a Bias tee to work properly.

Do you also need a RF Bias Tee between the adapter cable and the GPS antenna?

Hi Anthony

You'll need a Bias tee if the antenna is active. You can take a look at the nRF91 DK hardware files to see how this is done there.

Best regards,

Simon

Hello, Simonr.

It is currently impossible to find the MXHS83QE3000. Can you recommend us some appropriate replacement for this adapter?

Thanks in advance!

Bojan.

Simonr, you should be clear enough and specify that all the external antennas you mentioned are active antennas and all of them need a Bias Tee for proper work. So it is not only antenna and adapter but antenna + adapter cable + Bias Tee if antenna is active (all antennas you listed are active).

A lot of confusion is distributed over the forum (from thread to thread) when you share the infos that are partly correct.

Cheers!

Tallysman also manufactures Bias-Tees
