Signal strength is how powerful the signal is getting to your box. Signal quality is how good a digital signal it is. You can have a rock crushing signal strength on digital terrestrial but a rubbish signal quality due to atmospherics and multipath reception. The coax from your aerial on the roof may or may not be good for digital depending on your area. There is a website to check by postcode but according to my aerial installer it's not terribly useful as things like new buildings change so quickly. The coaxial output from Virgin Media/ntl:/Telewest is unsuitable for Freeview reception.

Analogue TV has got by since 1950 with so called TV low loss coax. Typically brown, cheap and nasty, it has served us well, but no longer for the digital age. All you need to know for DTT is to use WF100 or CT100 satellite cable.
Don't EVER user brown unspecified TV Low loss coax.
You naturally ask yourself why I am recommending you should spend double on satellite cable? Impulse interference. It comes from the neighbour's central heating thermostat, the kid next door's moped, your own light switches. On analogue, all these little sparks of interference gave you a short line of black or white flecks for a few lines or so on one frame. With DTT you get a freeze frame of half a second or more. and that hacks you off far more.
Good cable is properly screened. With DTT it is not just the loss from aerial to set that matters, how well the cable keeps out interference is key to your viewing experience.
