How to fit an F type satellite compression connector to coax cable.

This tutorial on how to fit a F type satellite compression connector to coax cable, something that is asked on a regular basis here at Sats UK.

  • First Strip back the cable, about 1/4 inch core and 1/4 inch dialectric.

  • Next fold back the outer braid, with some F connectors you may need to remove the foil shield, but others will be fine with it in place.

  • Push on the F connector with the braid still pulled back over the outer, Tip a warm cable makes it easier.
    (If you have a screw on type “F” Connector, simply screw the F connector onto the coax cable until the dialectic foam core touches the end of the connector barrel)

  • Then insert the cable into the crimping tool and crimp.

  • Your finished satellite F connector should look like this.-

Hello chris,
The foil should definitely stay on the dielectric. In your variant, the return loss and the shielding worsened.
The press plug has dan only mechanical sense.

In practice I find (with screw-on plugs) that the foil cracks away and has to be removed to simply tidy up the installation. I can't see how the return loss or shielding would be worsened as the whole of the end of the cable will be enclosed by the plug.

This is using WF100 with copper foil so aluminium foil may be less prone to cracking however I still wouldn't worry about it.
I'm sorry that I wrote something about it. I just thought that a faulty assembly instruction is visible to everyone, not so good. Of course, anyone can mount his plug as he pleases.
@PaulR: A screwed plug has a shield of max. 75dB. If you remove everything from the dielectric, you have a weak spot there. Then you do not need a cable with 100 and more dB shielding. With the increasing number of LTE frequencies, interference can quickly occur.
If you do not like this well-meant hint, delete my posts on this topic.

I don't see any reason to delete the post. I was really just pointing out how, in practice, the copper foil tears and then has to be removed anyway.
Ref the copper foil shielding, I have found that that in genuine Webro WF100 is reasonably flexible, whereas that in some generally similar CT100 (notably, Farnell's own brand stuff ) is rather more brittle and cracks easily (and so I won't use that anymore).
Another issue is that with many screw-on connectors, the inner barrel can be too narrow to allow the dielectric to enter with the foil still on it.
