We may be living in the age of internet television that can be accessed through smart phones and TVs but there are many among us who still rely on the trusty old terrestrial television. With an antenna, we can catch over-the-air programs on our favorite channels for an affordable subscription fee. The right antenna can change the way you watch television. It can deliver better reception to give you value for money while ensuring that you pick up all the signals subscribed to. Take a look at the options available to terrestrial TV subscribers along with which are meant for indoor and outdoor use. Dipole The dipole is a very simply designed antenna. It is further divided into several subtypes like bowtie, loop and folded-dipole. The bowtie has a wider bandwidth while the loop and folded-dipole assure better efficiency. A big advantage of dipoles is that they're physically balanced. They can pick up signals of different frequencies and reduce the chance of receiving conflicting signals. They can also move and slant to receive more signals which a stationary antenna will have difficulty with. Stacked dipole A stacked dipole has more than two dipoles in a single unit. It can receive wider signals (more gain) than a single dipole as long as the poles are precisely slanted and not too close to each other. Stacked dipoles are arranged vertically, horizontally or end-to-end. LPDA LPDA stands for log-periodic dipole array arranged end-to-end or in a V-shape. It can receive a wider range of frequencies while maintaining moderate gain. LPDAs are occasionally used as very high frequency (VHF) or ultra high frequency (UHF) antennas. VHF is used for marine communications and air traffic control communications aside from television broadcasting while UHF is used for satellite communications, cordless phones and also in television broadcasting. Reflector Reflector antennas increase gain in a given direction while standalone reflectors redirect radio frequency. A very common example of reflector antennas is the satellite dish which receives microwaves from satellites to transmit satellite television signals and satellite communications to vehicles, ships and planes. Satellite antennas are of several types such as multi-satellite, motor-driven, VSAT and DTH. Indoor and outdoor Aside from the types of antennas given above, some are only meant for indoor use while others work better in the outdoors. Dipole antennas, including loop, are generally intended for indoor use while LPDA antennas are installed outdoors. Directional and multidirectional Antennas are either directional or multidirectional. The first is chosen if the antenna is situated around 25 miles or more to the nearest TV tower. It's more commonly used in rural areas, allowing receivers to tune the antenna precisely in one direction. Multidirectional antennas are used to receive signals from television towers located less than 25 miles. They pick up signals from different towers and are most often installed in urban and semi-urban locales. Installing a basic antenna can be done by amateurs although professionals are able to achieve greater precision and a reduced chance of 'ghosting' (a 'visual lag'), the blurry images commonly found in analog televisions. Professionals will also recommend the use of a good lightning arrestor, a device crucial to helping direct lightning away from antennas and wiring. Consumers would do well to know that antennas are very good conductors of electricity so it's important that arrestors are installed for safety.
