![]() We sometimes get people insisting that crimp on F connectors are superior to screw on types. NOTE : It is not unknown for the nuts to pull off the body of F connectors (all F connectors….), so our advice is order more than you need ! Alternatively we can attach the plugs for you at a small additional charge, see Custom Cables. I actually think fitting CoAx plugs correctly is not that easy, here is how to correctly fit a CoAx plug. If you have an intermittent signal it’s always worth checking the CoAx plug as a loose fitting one can cause this symptom, it may be a low quality plug or it was not even attached correctly in the first place ! Whilst checking the plug examine it for signs of water/dampness, this is usually caused by a damaged downlead, see “ clipping cable to the slates”. It is not advisable to reuse CoAx plugs as the " claw insert" becomes deformed when it is screwed up onto the cable, they aren’t that expensive anyway. The alloy ones can become difficult to undo over time, particularly if the atmosphere is damp or water has seeped down your aerial cable. We prefer brass plugs rather than alloy ones as they are more resistant to corrosion. One sign of a good quality Co-Ax plug is if the "claw insert" is brass, as opposed to one of those horrible shiny metal ones which don’t seem to grip as well. That said, it is true that the fact an F connector is screwed on does mean that the lead is less likely to become detached and furthermore the loss may be marginally lower than for a CoAx. Just put a CoAx on it, let’s be honest, they’ve been perfectly OK for the last 50 years or so (make sure it’s a reasonably snug fit though) ! And if anyone tries to tell you that CoAx plugs are unsuitable for UHF frequencies or that their impedance isn’t 75 Ohms, believe me they’re talking bollocks. That said, if your TV or amp has a CoAx input it is pointless putting an F connector on the end of a cable, then an F to Co-Ax adapter to turn it back into a CoAx. Note, albeit rarely, CoAx connectors are sometimes called as "Belling Lee" connectors, and also, somewhat inaccurately, IEC connectors.Ĭo Axial plugs are more convenient (as they are quicker to connect) but an F connector gives a more robust and positive connection, this is particularly important in the case of connections which require power pass. ![]() F connectors can also be used in place of CoAx plugs (assuming there is a corresponding F socket obviously ! ) but it is very bad practice to use CoAxial plugs/sockets for satellite work. ![]() ![]() Push in CoAx plugs can be used for TV (UHF) or FM/DAB radio (VHF), though DAB actually uses F connectors in most cases. ![]()
