Satellite TV rules the roost currently as most households use this technology to get their daily dose of their favorite shows and news. Life without it would be hard to imagine. Satellite TV, though popular, has some competition with other contenders like broadcast TV and cable TV who are also in in the fray. After all, consumers can never get the best if there is no competition in the market, as one player tries hard to outdo the other. To make matters simple, we will take a look at the essential differences between satellite TV and broadcast TV for starters.
Both technologies are premised on the same basic concept. The concept is simple – to wirelessly transmit television signals to the comfort of your home which you can view through your fancy television set. The similarity however, ends there. Broadcast television picks up signals from, you guessed it, broadcast stations. Unfortunately, the range of broadcast TV is limited as the radio signals that broadcast antenna catch are emitted in a straight line. Now buildings and trees will not hamper reception but when the world itself is not in agreement, these are petty players in the game. In other words, the shape and curvature of the Earth itself is detrimental to broadcast signals as they work in straight line and well, the Earth is not flat. While the viewers of broadcast TV can easily pick up signals with a small antenna, this looming problem of signal distortion over distances has always been the bane of broadcast television. Had the earth been flat, broadcast television would have worked like a charm. Unfortunately, the troubles of straight line broadcasting are not limited only to the antenna and the broadcasting station. The same issue prevails for viewers as well, which means that if the antenna is not close enough to the final output device or television set, the images streaming into the television set will also be distorted.

This is where Satellite TV scores over broadcast. Instead of transmitting through broadcast stations based on the ground itself, satellite TV has made the skies its home. Transmitting via communication satellites orbiting almost 37,000 km above the equator, satellite TV nullifies the shape of the Earth or any other inane problem you might throw at it. That is perhaps the main reason why satellite TV scores over broadcast. Satellite TV uses the similar premise of broadcast technology but applies it differently by taking into account the handicaps of broadcast TV.
