WF100 is Webro
I have "F" type connectors at my wall outlet - these are the so called "satellite" screw thread type - see the picture - & a better connection in all respects, maintaining 75ohm, more secure & easier to install than those 'orrible Belling-Lee plug in things. I have not found a better/worse F connector make, but I would go for a good quality wall socket such as MK. Also be aware that if you have an existing wall socket position that you intend to use, the metal back box might not be deep enough to take the more bulky RF screening cover of the new socket.
The NAT will need a female to male Belling-Lee, but instead of a straight one, think about a 90 degree angle as a possible better way to dress the cable to the NAT
