Identify SMD RF Connector

Hi, I have a SmartPill DataRecorder with an SMD antenna connector inside (434MHz antenna).
This one is a photo of the smd RF connector that I’m trying to identify:

side view:

I bought a 434MHz antenna with a UFL pigtail ( ) but the pigtail of the antenna is too tiny for the SMD connector of the data receiver.
To me (but I’m not sure), seems to be the same type of connector as the one on the antenna (U.FL (UMCC), IPEXMHF1 in the digikey page), but bigger.

Anyone can help me to identify the SMD RF connector and the relative pigtail mate?

The diameter of the connector it’s about 3 millimeters.

thank you

Hi cl.saragaglia,

Looks like an MMCX connector. Take a look at this one:


Here’s a possible 433MHz antenna with an MMCX connector to consider:
