Permanent alternative to F plug

I suppose you don't want to terminate them on wall boxes and then plug in extender cables from there?

I recently came across this:

Another option (depending on the aesthetic) is skirting trunking, which can be easily removed if access is needed.

Correctly fitted f plugs that are the correct size for the cable won't fail. Use two f plugs and an f line connector. Use the tug test. Wrap the whole thing tightly in self-amalgamating tape.

R D S submitted this idea :

Make a good solid f-plug pair of ends off, joint them with a f-plugback to back barrel connector, test them, then add a layer of self amalgamating tape over the top to keep moisture out.

Snap!

Fitted correctly they don't fail.

Hmm, interesting. Why self-amalg tape and not heat shrink sleeve?

Heat shrink is not necessarily air tight (although adhesive lined would be ok). It's not massive mechanical protection you need so much as atmospheric.

OK the sticky backed heat shrink sleaving, it is better able to seal and keep moisture out.

I have fitted BNC conectors to many GHz devices.

OK, They spent a time in a slightly damp corner* behind the TV, probably getting shunted about now and again, on a couple of occasions we'd no signal and I found myself trimming and reattaching. I'll do a better job of attaching them and seal.... Cheers.

If the cable end has been in a damp place the whole cable might need replacing.

Self-amalg takes a bit of practice to apply correctly, but I think it does a better job when used right.

F plugs are surprisingly good if they are fitted correctly and not being repeatedly undone etc.

The simple ‘twist on’ ones can be unreliable due to poor fitting. There is a type which needs a cheap tool, I think I paid a fiver. The tool forces a part of the connect under the braid and grips the insulation.

The ‘special’ plugs are a bit more expensive but still cheap.

Wrap them in self amalgamating tape.

I had to undo one done like that recently - had been exposed to the elements for many years. Was in perfect condition.

I may be wrong, but I think that the black ones are more than good enough for the job, but the blue ones can be used, un-protected, outdoors.

Poor fitting means it's the wrong size. Beware of using one that's a bit too small because the internal thread can cut the folded-back braid.

It's a goldilocks thing.
