What Does Yagi Antenna Mean? A Yagi antenna is a directional antenna consisting of a driven element such as dipole or folded dipole and additional parasitic elements, typically a reflector and one or more directors. It radiates in only one direction and is most commonly used in point-to-point...
A Yagi antenna or a Yagi-Uda antenna, is a directional antenna that radiates signals in one main direction. It consists of a long transmission line with a single driven element consisting of two rods connected on either side of the transmission line. It also consists of a single reflector on...
What Does High-Gain Antenna Mean? A high-gain antenna (HGA) is an antenna with a narrow radio beam that is used to increase signal strength. High-gain antennas provide a more precise way of targeting radio signals and are therefore very essential to long-range wireless networks. They even...
J pole antenna : This type of vertical antenna is a convenient for of vertical antenna. It provides some gain over a quarter wave vertical and has the advantage that it does not require any radials or some form of ground plane against which to operate. Vertical dipole: The vertical dipole...
One of the main forms of antenna that is balanced is a dipole antenna. This form of radio antenna is used in many radio communications applications on its own as well as within other forms of antenna such as a Yagi (Yagi-Uda) antenna, and many other types of radio antenna. In order ...
What Does Antenna Array Mean? An antenna array is group of antennas connected and arranged in a regular structure to form a single antenna that is able to produce radiation patterns not produced by individual antennas. Advertisements Antenna arrays are groups of isotropic radiators of ...
T section network: The T section antenna tuner using a single inductor is able to match a large range of antenna impedances and and introduces little loss. As a result it has been popular at various times. It is actually a high pass configuration, which does not provide any attenuation of...
Doublet antenna showing use of ATU with balanced antenna connection The antenna tuning unit used should be able to match impedances over a wide range, and it must also have a balanced output connection. If it does not, then an external balun is required so that the unbalanced to balanced...
As a guide a 30 metre length of RG213 coax with a loss of around 1.5 dB at 30 MHz will mean that an antenna operating with a VSWR will only give a loss of just over 1dB at this frequency compared to a perfectly matched antenna....
