Mike Davison:
As the Belmont signals appear first during the automatic tuning process, many TVs set those as the 'default' services but when it find similar ones from a different transmitter they usually get entered into the Channel Guide on different Logical Channel Numbers (LCNs).
The way round this is to look up the actual transmission channels for the wanted multiplexes, see the top of this page for those relating to Waltham, and then manually tune those. Check your TV manual for how to perform a manual tune, it varies between sets.

What you appear to be seeking is a UHF combiner. There are some available but make sure you get one that is matched for 75 Ohms impedence and not 50 Ohms (that is suitable for satellite IF and not UHF TV signals).
There are a number of manufacturers offering potentially suitable combiners. Note that the best type are powered to avoid signal losses, especially important oif you are in a weak signal area.

Vince and Carol:
For anyone to offer meaningful assistance they need a full post code of your location or that of a very nearby shop or post office. That is so that we can determine which transmitter you may be using and whether there are any engineering works or line of sight obstructions.

Brown:
Look at the blue boxes below your posting and open the one named 'digitaluk trade'. That will show the compass direction for your local/preferred transmitter.
Have the aerial installed using that bearing and ensure it is correctly aligned and set with the polarisation correct. Note that you would be best using a log-periodic aerial for future reception.
Do not fall for the scam of a 'digital aerial' there is no such thing and is a marketing ploy to charge more for the same aerials! Depending on your exact location, you may need to avoid having large buildings between you and the transmitter, some of the tower blocks in Glasgow can be a problem.

Can I stop paying Sky and use my satellite receiver to get Free

No! Sky does not use an aerial, instead it uses a dish and LNB combination to receive signals from a set of satellites in geo-stationary orbit on the Equator above East Africa. Normal Freeview recpetion requires the use of an aerial of a Yagi or log-periodic design aimed at your preferred transmitter. 'Preferred' here meaning the one that gives the best reception.
If you enter your full post code into this website you will be shown listings of available transmitters and which direction to have your new aerial aimed for best reception.

I presume by 'aries' you really mean an aerial? Is it a shared aerial as suggested by your posting? Do you mean it is a communal aerial shared by many dwellings in a block? Did you have a previous Freeview TV connected to the same aerial system? Di that get the channels mentioned?
Have you asked whether your immediate neighbours have the same problem? If they have then it may be that the communal aerial has a fault and that should be reported to the owners/managing agents of the property.
From time to time, essential engineering work has to be done and that sometines means recpetion of some or all signals is affected. To find out if that is the case, then we need a full post code of your location or that of a very nearby shop or post office.

What is the Inversion Effect and why does it effect my Freeview

Anje and Alexei:
One possibility could be that you are too close to the transmitter and have too much signal. Try searching this website for 'too much of a good thing'. You should also give yopur full post code (or that of a very nearby shop of post office) so that the relative locations of your equipment and the transmitters can be determioned, plus allowing a look at the local terrain which can sometimes cause such issues.

To assist you we really need to know where you live in relation to the transmitters. To help us do tat please enter a full post code, or that of a very nearby shop or post office, so that we can examine the preferred transmitter (I'm not aware of any called 'Carson Hill') and the signalpath to your aerial.

Tony Dix:
It is definitely not Rowridge as all the signals from there are on channels below 40.
It may be coming from Huntshaw Cross or Mendip. Both use Channel 56 for a full multiplex. Mendip transmits at 100kW so is the more likely source. That means it it is being received via a back lobe of your aerial's receiving pattern.
I suggest you do a full manual tune of the channels listed for Rowridge at the top of this page.

SJ:
It is unwise to mix cable types for satellite downleads. The UHF coax is poor at the frequencies used for the connection between the LNB and the satellite receiver inputs. The change in presented impedance at the cable junction can give rise to unexpected effects, such as some signals not being receivable but others seeming OK.
I would recommend changing the UHF (conventional TV) cables for satellite flyleads using 'F' connectors fitted carefully to avoid short circuits. You can use 'F' to 'F' couplers to join cables together but try to use only one maximum in each lead.
The problem you report could well be because of the use of TV cable and not satellite cable.
