HOW TO FIT A WF65 F CONNECTOR 

If it's twin cable split the cable approx 50mm from the end

Score the outer sheath along its length approx 25mm

Then peel back and remove exposing the copper braid/foil

Pull the copper braid toward one side and the copper foil toward the other side

Cut the copper braid and the copper foil approx 10mm

Fold back copper braid toward one side and the copper foil toward the other side - towards the length of cable

Score the foam cable around approx 3mm from the copper braid/foil , Then Strip the foam from the copper core 

At this stage make sure that none of the braid comes in contact with the copper core

Introduce the F connector over the end of the cable

Twist the F connector on to the cable over the copper foil/braid, clockwise with a little presure until the foam start's to appear inside the connector and the braid is covered by the slim part of the connector

Trim off the protruding copper core and its ready for connecting
