Hi

Probably a simple question, but anyone know how this works to join two parts of a cut coax cable please?

Cheers

For a terrestrial TV lead:

Either use a male & a female or two males & the joiner. For a satellite cable:

Badly! wink

Joking aside, coax is used to carry high frequency signals and they are susceptible to interference hence the use of shielding. Using a plastic connector like that breaks the continous shielding and so could cause signal degradation. You would be better off using a couple of screw-on F-connectors and coupler e.g. this. There will be plenty of guides and videos online showing you how to correctly prepare the cable and assemble the connections.

Edit: Apologies, didn't see there were already other replies (and saying the same thing)!

Cobblers. There's literally millions in use connecting TVs all round the world.

We’ll have to agree to disagree on that one, it’s very easy to create a poor connection to the cable itself and the mechanical connection with the joiners is sketchy.

If you look back at the Sky Magic Eye remote repeater that was powered over coax, a single connector like those would drop the power enough for it not to work.

Depends what the coax is doing.
In many cases the proper answer is a new piece of cable.
Coax is prone to corrosion of the braid, which is lossy for high frequency signals.

Both the F connectors and the 'TV' type are pretty poor really, but often do the job.
Covering the join with self almagamating tape helps.
The connector needs to fit the cable, in terms of diameter.

There's a world of difference between 'good enough' for a TV in a good signal area, compared to a measuring system or a radar.

It's true that neither the Belling-Lee or the F-Type are the greatest performing connectors ever invented but in the context of designing a connector that almost any muppet can make off with no special tools and reasonable chance of success they are pretty successful designs.

Make sure they are the right size for regular type coax.
