Amplifier is an electronic device using transistors or electron tubes. This is used to produce and amplification of an electrical signal. It also increases and restores the strength of the signals passing through it. It involves the controlled conduction of electrons especially in a gas or vacuum or semiconductor. An amplifier uses a small amount o...
Before eternally mounting the antenna for digital television reception it is a good idea to perform a quick view survey to find the spot with the best signal. Moving the antenna one way or another just a few feet can make a wonderful difference in the success of the antenna installation. Digital television is a little different than analog TV. With...
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...
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...
Antennas are the electronic devices used to transmit and receive radio signals. They are the important and essential component for a home. The antennas are responsible for providing good and proper signals. There are many types of home antenna systems are available.
1. Normal antennas:
These are the antennas usually used to receive ra...
Antennas are the electronic devices that are used to transmit and receive radio signals. These are electrical conductors for radio waves. Heinrich hertz discovered antennas in 1888. He discovered the antennas to prove the existence of electromagnetic waves. They convert radio frequency electrical current to electromagnetic waves and vice versa. The...
Being able to talk on a handheld gadget without wires crossways the world is really a great achievement in technology. Few people stop and imagine about this minor miracle. However, when someone stuck somewhere unable to make a call because of a poor cell signal, the appreciation for this technology can be tested. Regrettably, cellular service prov...
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...
