Digital Signal Is Not As Robust

The Digital Signal Is Not As Robust As The Analogue One.

An analogue signal can be really quite poor and you still get a watchable Picture. It may be grainy and maybe even ghosting but it’s there to see.  Seriously in my job I have been to people’s house and they have been watching a snowy grainy fuzzy SBS picture for years and just putting up with it.  A digital signal will not degrade in the same manner. Generally you will either get a perfect picture, or you will get very annoying blocking/freezing and nothing but “CHECK Antenna” Or “No Signal”

Digital transmissions have in-built “error correction” which can overcome A certain amount of signal degradation. However, once that error correction Data has been exhausted the picture has no alternative but to fail … and spectacularly. This is known as the “digital cliff edge” and it is why one should go for the Best antenna, the best cable and (if required) a decent screened amp/splitter. Any one of these may (normally) only make a marginal difference, but If they keep your signals on the right side of that “cliff edge”, then for what They cost, it is an excellent investment

Digital TV Signals Do Not Like Dips, Trees, Power Lines Or Other Things In Line Of Sight, also if you have a tin roof its advised to go for a slightly high pole than a tiled roof house. You don’t want to be on the wrong side of the cliff edge as watching your TV will be like watching a dodgy Bali pirated DVD that skips pops and is just unwatchable
