WHY IS SOUTH EAST ENGLAND LAST TO BE CONVERTED!!!

Nah not that lol but that pizz's me off being the last o well


First off i diy'd my digital aerial myself & had all the decent (i watch)channels, but some like film4 = was abit blocky sound cutting at times & that, the aerial was on the side of the house (dont ask!) afew months ago i had digital installed in all bedrooms & now the aerial is on the roof (chimley where it belongs ) im missing afew channels, BBC1-2, BBC THREE & afew other odd ones

Q is.. been wondering is the digital signal going to be stronger when all converted? say like if you bought one those poxy indoors aerials you would still received pukka signal from digital?
