The omni directional antenna is an antenna system that radiates power uniformly in all directions. The only 3 dimensional omni directional antenna is the isotropic antenna, a hypothetical construct derived from actual antenna radiation patterns and used as a suggestion for specifying antenna gain and radio system effective radiated power. Practical...
An antenna that is able to receive signals from many directions is called a multi directional antenna. There are many size and shapes of multi directional antennas. They have different features. There are mainly two types of multi directional antennas, one being the indoor antenna and the other being the outdoor antenna. The indoor antennas can be ...
Television antenna signals are strongest and reception is generally the best when the station's transmitting tower is in clear line of vision with the home receiving the broadcast. Mountains, buildings or trees that block this line of sight tend to weaken and degrade the received signal. The signal also becomes weaker as it travels further from the...
Antenna is an electronic device. It is an arrangement of aerial electronic conductors. These are designed to transmit or receive radio waves or electromagnetic waves. Heinrich Hertz discovered an antenna in 1886. Basically the antennas convert radio frequency electric current into an electromagnetic wave. Antennas have a wide range of usage. They a...
One can build wireless home network, a wireless LAN by using simple three-step approach like identify the WLAN design that is best for the situation. Choose good wireless gear and install gear and test the configured WLAN. Though prices have dropped severely from a few years ago when wireless gear was quite expensive. Benefits of Wireless: Wi...
The best way to describe a basic television antenna is low tech. Television antennas feature a series of fundamentals cut to exact lengths which are designed to receive a attuned frequency from a transmitted television indications. Each element has a pair of metal rods extending from an explosion. The main difference between various brands of telev...
HDTV is high definition television. A HDTV antenna is a regular TV antenna used for HDTV reception. It is an essential component of home entertainment system. The HDTV antennas are helpful in providing digital pictures without any disturbance of noise. The HDTV antenna picks up an HD signal. A HDTV antenna is typically a high quality antenna. There...
The term grounding means a common return path in electrical circuits. Electricity grounding is nothing but the connection of part of an electrical circuit to an electrical ground. There are three types of grounds, static, RF and electrical. Static grounding is the most difficult. There will no be guaranteed results. The electrical grounding is t...
There are many indoor concrete buildings with no windows within 35 feet of the cellular phone units. Criteria for these new locations include low or unsound signal without the antenna booster installed. Tests conducted for indoor functionality of the antenna booster spanned over a period of time of no less than a couple of months. The rationale for...
The elements of the antenna array means the collection of all the similar radiation and elements related to the antenna, where the counting of the elements starts from 1 till N number. The similarity of the elements is judged on the basis of the same frequency, which means to derive voltage of each element one has fixed amplitude and phase angle. T...
