You can buy f-connector from places like maplins , and they have an internal thread on them , so you can just screw them on and they grip the outer casing of the cable , no special tool required m8 .

Splitter also available at maplins , but you will probably have to order some as they nearly always out of stock lol
Look for the screw on f-connectors on ebay... theyre a couple of quid for about 10 (including delivery).... Loads cheaper than maplins (who want £1 each)
