I'm looking to add a pigtail and larger antenna to small wireless video receiver. It came with a removable antenna with a connector I don't recognize. Sorry for the blurry pictures. If they're not helpful I can try again. It's a push on, and the center of it has the white plastic bit I've seen on RP-TNC connectors. The numbers on the tape in the images are centimeters.

It's quite hard to tell but here is some hints on possibilities:

The connector you have seems to be to long for the small U.FL, also the U.FL central pin seems to big to fit your connector.

I'll said that's a MMCX connector but not sure at 100%.

  • \$\begingroup\$ Dimensions seem to match with MMCX. For example on the photo the part of the connector which extrudes from the insulator is about 4 mm long. This image under F shows the length of 4 mm to 4.12 mm. The diameter seems to be close as well. Also it's waaaay too large to be U.FL connector. They're just a few mm thick long. \$\endgroup\$

  • \$\begingroup\$ I haven't had time to go buy an mmcx pigtail, but I agree that looking at various images online, this seems to be right. I'll mark this as the correct answer for now. \$\endgroup\$
