Ah ok, this is making some sense, so the Humax box is a satellite receiver not a digital signal receiver from a digital aerial. So options would be as you say, to either get a dish fitted (Not sure if he can at the moment) or get a freeview recorder box that uses a digital signal not a satellite signal
There is no such thing as a digital aerial. UK terrestrial TV uses the UHF band for transmission. Former analogue services used a single UHF carrier (the carrier is analogue). An aerial is designed to receive a range of UHF carriers.
When analogue TV shut down the same type analogue carrier is used. But instead of one frequency carrying only a single channel. They carry lots of of channels on the same carrier (known as a MUX - Multiplex). That's because the info is encoded digitally. Digital tuners extract a channel from all the data to provide a TV signal.
Satellite is also digital. The digital mux use a much higher frequency (actually similar to a microwave. These are too high a frequency to use coax. The signals are transmitted from satellites 22000 mls above the equator.
The dish focusses these on a device called a lnb which block shifts the frequency down to level they can use to deliver the signals directly to a satellite tuner.
Thereafter the process is the same as terrestrial. The tuner extracts the channel you want to display it on a TV.
Both satellite and terrestrial are digital.
DVB- stands for digital video broadcasting. There are two variants used for each 1 or 2.
So
DVB-T is digital video broadcasting- Terrestrial (the 1 is implied). DVB-T is used for terrestrial Standard Definition content
DVB-T2 is digital Video Broadcasting version - Mostly used for HD services but not always. Some Freeview multiplexes have SD as well as HD channels.
DVB-S is digital Video Broadcasting version 1 again the 1 is implied. Used for SD services
DVB-S2 is satellite digital Video - V2 . Used for HD services
The Foxsat-HDR is a twin tuner DVB-S2 unit with a built in hard disk used to record two and provide live TV pause and rewind capability.
The FVP- unit I linked to has triple DVB-T2 tuners.
If your dads TV has Freeview-HD it will have at least one DVB-T2 tuner.
If only SD capable of viewing SD channels it will likely have a single DVB-T tuner.
The FVP unit I linked to is a triple tuner FVP-
