Michael, it is always possible that someone set your UK Plus/4 to be an NTSC machine. Unlikely, yes.... but possible. The easiest way to know is to check the ROM in socket U24. If it's 318005-05 then it's NTSC, 318005-04 is PAL.
The video processing chip ("TED") is compatible with both systems, but has to be told somehow which system to display in. The ROM I mentioned is the chip that tells TED to be PAL or NTSC at power-up.
Going through the DIN connector to a SCART would be a better picture on any television, so that is the preferred method anyway. Using the RF cable is really a "poor man's" television adapter.
