TV Antennas

A satellite dish is a dish-shaped parabolic antenna that receives signals from satellites and routes them into the converter. The general rule is that larger dishes are better at catching satellite signals, so a sufficiently large dish can receive signals even from distant satellites, whose signal at the receiving location is rather weak otherwise. Dishes are usually made of iron or aluminium. Aluminium dishes are lighter and immune to corrosion, while iron dishes are cheaper, but can rust if exposed to elements. A dish should be mounted on a bracket or pole.
