FreeSat after Sky Subscription.

From reading other posts here, it is probably the LNB which will need to be replaced.

You might have a hybrid LNB which has two wideband outputs and the remainder as standard ones. In that case, you'd need to swap the connections on the dish.

That's correct, if the LNB is of that type.

If you install a genuine Freesat receiver it will work with the existing SkyQ cables, it will give you access to 4 tuners for watching/recording.

The 2 SkyQ cables carry the horizontal and vertical polarised channels separately from the wideband outputs on the LNB.

This option means no changes to LNB or other connected receivers

Just on the terminology, Freesat is a proprietary satellite service in the UK that carries the UK channels with a 7 day EPG like Sky and channels pay for the privilege of being carried on the service. It was developed as a backup to the UK's terrestrial Freeview service, for areas not covered by Freeview and areas not covered by the full 6 multiplex Freeview service.

Your other boxes, TV etc are free-to-air (FTA) satellite receivers that simply tune in the freely available, non-encrypted satellite channels in no particular order with no 7 day epg

Good advice.

If its been up there years expect corrosion on it as most installers cut off cables and attach a new lnb with new connectors.

Dont forget your skirt to pull down after to help protect it.

Those look like crimped connectors and are there for life. If you get them off they may not even be re-usable. The easiest solution is to cut the cables and refit with F connectors but wait for a while and others may come back with an easier solution. As they say you can live and learn.

Its actually a very good job and they crimped the legacy as well.

The bit you push up is the weather shield and its designed not to be removed.

Do you still have contact with the fitter? Dish looks easy to access just make sure you cut the 2 on the wideband outputs.

Don't cut the cable, just get a pointy nose pliers or spanner onto the silver part of the f-connector to the LNB and break the lock, it should screw off easily enough.

The connector is crimped to the cable, if you cut it off you have to get new screw on connectors

Personally I can't give you any specific advice on the hybrid LNB as I've never had any direct contact with them. Hopefully someone will give you hands on advice.
