VHF and UHF TV Antenna

Television antennas usually has a pair of metal rods (made primarily of alumunium) extending from a boom. The quality of the antenna is depends on how well anodized the metal is. When the metal oxidizes, you will almost always experience inadequate reception. Outdoor TV antennas are more prone to wear than their indoor counterparts although outdoor TV antennas provide additional reliability and clarity. The main factors determining reception are the direction and distance from the television station transmitters to your antenna, as well as the transmitter’s power. Indoor antennas are gennerally small, designed to be placed on or near your TV and can be affected by wall insulation, roofing materials, plumbing, electrical wiring and even people moving around a room. Other sources of household interference include computers, fluorescent light, and cordless phones.
