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.
