ANTENNA
As a receiving antenna also suitable for sending and vice versa. Some designs prevent a reciprocal use. The size of the antenna elements is aimed primarily on the wave length, so the frequency is a very important criterion for the selection and construction of an antenna.
Species: Among the most well-known species, there are reference antennas, space antennas, linear antennas, reflector antennas, antennas and magnetic antennas. By the way, an average antenna, is an outdoor antenna. The breakdown of antenna designs can be determined by a lot of points. Usually it is after the geometry of the antenna. It can also be other criteria such as its bandwidth, directional characteristics and the operating frequency, etc.
Outdoor construction of antenna: In addition, one have to ensure that if outdoor antennas to be mounted on high towers, or high areas, which dominate the area, so they must precede lightning (thunderbolt) protected. Antennas offer strong wind and weather resistance, and therefore all antennas must have to be constructed very correctly and the antenna mast construction must absorb these additional forces. The newer model of antennas is the HDTV antenna. The putting up of an over-the-air high-def programming is easy. Because the most televisions can now display HDTV and are sold with built-in tuners. These are the so-called ATSC tuners. They can receive high-definition and very goog lower-resolutions (digital) broadcasts by the air. New models:
