The top connector looks like a "F" style and the bottom a European TV connector.
In any event, the most likely use is to provide pass-thru when the STB is off.
A manual would provide a definative answer.
If it was the US and it was a ATSC DTV converter box, the above would be true and the box would provide NTSC channel 3 or 4 output selectable with a physical switch.
The manual would be the source of information that you seek.

That was my thought - an analogue RF output - although it could well be UHF, and quite probably fully variable from a menu on the box - it all depends really where you are?, and if VHF is in use or not?.
However, it looks a pretty minimal low spec box, with just the two lowest quality outputs possible (composite and RF).
Technically, Is it feasible to design & construct a wireless Set Top Box product?
The Set Top Box interface audio, video connections will be wireless connections instead of physical wiring with the TV set.
The Limitations would be because of cable wire connectivity provided by the cable service operator which has to be hard wired physically with the Set up Top Box product?
