If you use an antenna to receive OTA television broadcasts, you have probably noticed some differences between analog and digital signals. For starters, digital offers a wider screen, decimal channel numbers, the use of DTV converter boxes, and so on.
How to Improve Your Digital TV Reception Using Amplifiers and Boosters
There's another invisible difference that can cause lost or inconsistent reception: digital signals are much weaker than analog.
Under identical broadcast conditions, a digital TV signal will not travel as far as an analog signal, because terrestrial limitations hinder digital more than analog. Things that affect reception include roofs, walls, hills, trees, wind, mountains, and other barriers.
A digital signal is so sensitive that a person walking past it can take it offline. In comparison, an analog signal needs more interference to disappear.
