im american so i have to deel with this smurfing digital signal switch over i have no interest in digital signal because every new tv i see looks all pixel-ated and the signal look no better

i know that air stations can look like crap (when it rains fox fails but when it snows it looks damn fine)

those converter boxes, do i need i per tv or could i hook it up straight to the antenna and then distribute it to the five tv's in the house?
