An outdoor television antenna is mounted on a rooftop to boost signal reception from neighbouring broadcast towers. If the roof is not accessible, an outdoor antenna can be installed on a tripod or a deck. An outdoor antenna offers several benefits over its indoor counterpart, including superior signal quality. Therefore, it is ideal for locations that are far away from a broadcast tower or transmitter. This article reviews some useful considerations when installing an outdoor TV antenna.
How It Works
Most broadcast television stations transmit signals using over the air (OTA) protocol. A TV antenna receives transmitted signals and converts them into pictures and sound. There are two common types of outdoor antennas, namely directional and omnidirectional. Directional outdoor antennas pick up signals when pointed in the direction of a broadcasting tower. Such antennas are ideal because they receive signals from long distances. On the other hand, omnidirectional antennas receive signals at different angles, but with a shorter range than directional antennas.
Benefits of Installing an Outdoor Antenna
Because installing an outdoor antenna can be difficult, consider hiring an expert installer to do the legwork for you. Besides, you will not incur the additional costs of paying for satellite or cable television. Outdoor antennas also produce clear images, which improve the viewing experience. Similarly, you can receive multiple digital television channels with enhanced quality to diversify your viewing options. Once purchased, an outside antenna can last for many years without needing replacement, saving you money in the long-term.
Signal-Blocking Obstructions
Since an outdoor antenna depends on OTA signals, anything that can block signals from reaching an antenna affects the signal quality and subsequently the viewing experience. Outdoor antennas should be installed away or above obstructions like tall buildings, cell towers, power lines, trees, and hills. Remember that the higher an antenna goes, the better the signal quality.
Signal Reception
You should know the channels in your area before installing an outdoor antenna. Several internet tools and websites can aid in your research, whereby you can enter your location to find out more about digital TV coverage. Another option is to talk to your neighbours to know more about the area's signal strength and the channels being transmitted OTA. Some TV transmitters might be too far for a standard outdoor antenna to receive signals. Therefore, you must research beforehand to get as much information as possible. When setting up an antenna, an installer will use tools such as a DVB-T spectrum analyser to measure signal quality and strength.
