Re-fitting 'F' end on to WF100 cable?

I can't seem to get it to STAY back on.

Bought the cabling from satcure on the back of advice here. Put everything in to place. It works.
The only problem is the end came off very very very easily.




Now i was just thinking of getting some superglue, sticking some in the end of the connector to the left, feeding the cable in & leaving it to set.

But i don't want to do that if there's 1) Chance it'll knacker the functioning somehow - i don't know how important that copper wiring is that's frayed etc and 2) There's a better option that I don't know about.


So to secure that piece on the left to the cable... (because it doesn't just push on & stay)?

That's a compression fitting, you need a tool to put it on. Screw on fittings can be found in most DIY shops.
Superglue or tape might work for a while if it's indoors.

Yes it's indoors.

Unless this tool is only a couple of quid (& i don't imagine it's going to be) then it's not really going to be a great idea buying it just to put this end back on i would imagine because i honestly can't see where i'd need to use it again.

All it is is this cable entering the living room from under the floorboards (i fed the cable through from outside, under the floorboards & up through a hole next to the skirting. Then a small cable, i think about 0.5mtr will go from the TV & connect to this cable via a coupling barrel. That's all it is.


If it was you what would you do? Get some gorilla glue on there (since i already have some) or buy a screw on connector?

I'd use a screw on connector, but try the glue first, if it doesn't hold just cut a bit of the cable off and buy a screw on connector, they don't cost much.

The type of plug you have there isn't a 'push-on-and -stay' connector. It looks like a compression plug, and it looks like it has been fitted wrong.

When supplied new the black ring at the back of the plug is extended out. The cable is cut with less of the white inner insulation than in your picture (only needs 3-4mm showing), and then the plug is pushed on to the end of the cable so the white sits at a flush level when looking in from the screw-on end. Inside the barrel of the plug there's a cylindrical metal collar that forces its way between the white insulation and the copper braid to provide a good earthing contact. The final part of the plug fitting process is to use a tool that compresses the plug down the long axis so that the black ring ends up where it is as seen on your picture. Doing that causes the inside tube to deform so that a donut-shaped ring grips the cable.

What has gone wrong with your installation of the plug is that the white insulation is too long. This means that the various mating surfaces are in the wrong positions to do their respective jobs: There's no decent earth connection. Also the donut (which is that is designed to grip on to the black outer insulation with enough force to hold the plug on without crushing the cable) won't provide any gripping force on the thinner white insulation.

Compression F plugs are a one-shot deal. If they're not fitted correctly the first time then throw away the plug because it's not re-usable. Either buy some more compression plugs and the tool (approx £20 - £160 depending on quality) and do it properly, or buy some screw-on F plugs and use those instead.

For one off jobs just buy the correct screw on type of connectors, satcure sell ones which they recommend as a good fit to their cable which I've found to be excellent, I'm sure they also provide good instructions on the correct fitting of them too. Glue etc is really not suitable at all.

Glue might cause a bad connection even if it does hold the wire. Get some screw on connectors.

As I have found out there are 2 cable diameters so get the correct plug.

Note that earth != shield. In this case, shield is the correct term.

A correctly fitted compression plug doesn't simply pull off. This fact suggests that you gave a darn good yank or else the lead was faulty. What was SatCure's response when you informed them? In my experience, they would send you a replacement without hesitation.

They are also quite open about any problems.
