How to fit 'F' Connectors to coaxial cable
As published in "What Satellite TV" magazine. About 25mm from the end, use a knife to cut around the outer plastic covering. Be careful not to cut the braided copper wires inside! Pull off the plastic cover. Separate the braided copper wires then twist them together in a "pigtail".
Cut off the exposed metal foil shield. Cut off the white plastic insulation to expose the inner wire core, leaving about 3mm of white plastic insulation. This reduces the risk of the braided copper wires touching the inner wire core which must never happen!
Push the copper pigtail back over the outer sheath and screw an 'F' connector over it as far as it will go. Make sure that the inner wire core can not touch the braided copper wires. Cut off the exposed pigtail.
Use sharp cutters to cut the inner wire core to leave about 3mm exposed. Make this cut at a 45 degree angle to make a point. This makes it easier to push the wire into a connector without risk of damage or bending the wire. Be careful not to cut yourself on this sharp point!
Push-on adaptors are available. These screw into an 'F' connector to turn it into a push-on plug. Useful when you are using a sat finder meter and also as an LNB selector (see below).
Right-angle adaptors are available. These can be used where space is limited - such as behind a wall plate.
'F' connectors outside MUST be sealed to keep water out, otherwise it will run through the cable, damaging the inside of the LNB and the satellite receiver. Water runs VERY quickly through coaxial cable by "capillary action". Be sure to use Self Amalgamating Tape. Cut off about four inches (100mm) and peel off the plastic backing.
Wrap the tape around the cable, just below the 'F' connector, stretching it strongly as you wrap in a spiral. Overlap by at least half the width of the tape so it bonds to itself. Continue to stretch and wrap it around the cable then the 'F' connector all the way up to the body of the LNB. (We used an "Alps" LNB for the demonstration).
Now stretch the excess length and spiral it back down the cable to finish off the joint neatly. As you stretch the tape to twice its normal length, you create energy that makes the tape melt into itself to form a solid rubber tube. You won't believe this stuff till you try it. There's NO glue. Also great for repairing leaking hose on car or washing machine! The only way to remove it is by cutting with a very sharp blade.
