set top box?

The set top box is connected to a cable or satellite service via a coaxial cable that has "F type" connectors on both ends typically. It is not connected directly to an antenna.

The input socket on your set top box will indicate which to use. Examine it.

If it is a simple co-axial socket which looks like the aerial input on your telly then you should connect it to the standard aerial cable.

If it is a slightly different, probably screw fitted input socket then you connect it to the NTL box with an appropriate lead.

Do not try changing the plugs to make it fit. At best that would not work, but it will possibly damage the equipment. They're different for sound technical reasons.

If neither cable seems to fit then you must get someone knowlegable to visit you and sort it out.

If it's a Freeview box then it's the socket on the wall connected to the aerial on your roof. Only ntl (Virgin Media) STBs (cable boxes) can use the ntl box output.

The aerial wire from your rooftop aerial should be connected direct to you TV, not the set top box! That way, you can view the terrestrial channels independently, and you can record a cable channel while watching a terrestrial channel, or vice versa.

the one that comes out of the ntl socket is your cable feed (in other words your cable channels) the arial input is for the one on the wall which is fed from your roof arial ( this allows you to recieve terestrial channels 1 to 5 even if your set top box is swithed off ( tune them into your tv manually).

there's a danger you may opt for a higher aerial relying on how solid the single is you've already got. you may examine how solid the coverage is on your section on the internet, do a glance for for freeview on google and this is going to elevate the area you opt for. yet aslo examine cable are all linked proper and go via the av channels. often times it helps to modify the freeview off for a couple of minutes and turn it decrease back on back.wish this helps!!
