Two F-Type plugs..
and an F-Type coupler...
Maplin will sell both.
Note that there is no seperate "pin" on the plug - the solid core of the coax forms the pin. Cut it to correct length after fitting.
Ideally the F-Type Plug would be a crimp on type but you may not want to fork out for the crimping tool so the top picture shows a screw on type.
Fitting instructions here..
http://www.tradeworks.tv/acatalog/F_connector_fitting.pdfbut instead of using electrical tape in the last step use heat shrink sleeve. Makes for a better job. Just remember to slide a bit down the cable before fitting the connector.
It can be a bit tough on the fingers getting the connectors on sometimes.
Coax cable actually comes in slightly different sizes. Mostly it's all similar enough that any F-Type connectors will fit but ocasionally it's a struggle. If there are any markings on the coax report back as we might be able to find the best ones to match.
