Some pictures of the connectors in question would be useful.

Good thinking!

The grid on my notebook is 5mm x 5mm, for those shots where the ruler is
out of the picture.

Overview - module with flylead



Detail of connector that mates with antenna cable.  The thread that is
visible is for panel mounting.



Detail of board-end of flylead and connector on board.



Couldn't get any closer with that lens...


Cheers

Looks like MCX.

I have connectors matching that description and general look on my
Oncore UT+, and I used a Garmin MCX-terminated antenna.

The PCB connector is probably an MCX connector.

The other end looks more like an SMB connector.

Another popular GPS connector is the MMCX.

I should mention that the two ends of the flylead both have a pin in the
centre of the connector and are of differing sizes.  The socket on the
antenna lead (not shown) has cuts around the edge for the flylead
connector to snap in, the socket on the board is solid.  The snap cuts
are on the plug.

That's that one confirmed, thanks.  Just fished out the antenna for my
Oncore modules and yes, it fits into the socket on the PCB.

Fans of Neal Stephenson (in particular Snow Crash) may consider this
as an example of "condensing fact from the vapor of nuance".
