I'm trying to identify the following miniature female RF coaxial connector found on an antenna input of a cheap DVB-T receiver (Sencor brand). I would like to identify the type so that I can get a matching male connector. The inner diameter of the receptacle measures 3.3 mm and the depth is approximately 4 mm. The inner surface is smooth. There are no threads or indents visible. Since it is on a DVB-T receiver, I'm guessing the connector probably has 75 ohm impedance.
Other dimensions I could measure with calipers (approx. where I can only do an estimate):
The closest match I could find is the front end of a SMC plug (without the threads), however the barrel is just slightly too large to fit (3.7 mm diameter). MCX also appears too large (3.8 mm).
Thanks for any help.

It looks to me like an MCX connector. For example, this one from Amphenol:
I'm not sure why this one doesn't seem to have the dielectric protruding around the center contact like yours, when it is shown in the general diagram below.
The 3.5 mm inner diameter you measured is pretty close to correct:
