Hi Ethel:
Your suggestion is perfectly possible. However, it can get a bit complicated setting things up.
The aerial connections are straightforward. The aerial is fed into the Freeview box and a fly-lead is fed from the 'r.f. loopthrough' on the Freeview box to the aerial socket on the TV. Theoretically, all that is then needed is a Scart lead from the Freeview box to the VCR and the set-up is (apparently) complete. (i.e. you can watch one Freeview channel while recording another).
However, you'll also have a Scart lead connecting the VCR to the TV. This is not only so that you can watch the programmes which you've recorded but also so that you can view the on-screen menus when you set up the Freeview receiver and the VCR. The TV might automatically switch to showing the signal from the 'Freeview box+VCR' part of the chain when one of these devices is active (rather than taking the signal from the aerial). If this occurred, it would be necessary to unplug the VCR-to-TV lead, after programming the recording, in order to watch a different channel on the TV (and then plug it back in later, to watch the recording from the VCR).
So it's technically possible but things might get a bit complicated.
