Radio antenna

The antenna is an arrangement of aerial electrical conductors designed to transmit or receive radio waves that is a class of electromagnetic waves. In other terms, antennas mainly convert radio frequency electrical currents into electromagnetic waves. Antennas are used in systems such as radio and television broadcasting point-to-point radio commun...
 

Outdoor antennas for household purposes

These are the antennas that are placed outside the house. An outdoor antenna can be slightly tilted to get better results of receiving signals. These antennas occupy large space. This gets signals directly from the satellite. Some of the outdoor antennas are good at receiving reflected signals. Outdoor antennas can be placed at the rooftop, railing...
 

Omni directional antenna

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...
 

Medium multi directional antenna

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 ...
 

Medium directional antenna

It is an electronic device used to transmit and receive radio signals. A directional antenna is an antenna that radiates greater power in one or more directions. This allows increased performances on transmit and receive and receive and reduced interference from unwanted sources. All the antennas are slightly directional. The normal antennas have a...
 

Loop antennas

A loop antenna is primarily used for the AM broadcast and the bands of Long wave. Mainly there are two types of loop antennas, among them one is ferrite bar same as the am radio and other is in the form of air core. A loop antenna is multidirectional. A loop antenna will receive the signals on the opposite side and off side of the antenna signal wi...
 

Installing a television antenna

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...
 

Indoor antennas for household purposes

Basically an antenna is an aerial. It has the main function to transmit and receive the radio waves.
It is an electronic device that converts the radio frequencies into electromagnetic waves and vice versa. Indoor antennas are the antennas used inside the home or any other such place. There are varieties of indoor antennas. All the electronic de...
 

How to improve TV reception

Reception is a process of receiving electromagnetic signals through antennas. If the antenna is placed next to the transmitter then there would be a perfect reception of signals. But it is not possible for everyone to have his or her antenna next to the transmitter. There will be a proper reception of signals in the nighttime. This is because there...
 

How to build antenna

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...
