Is there a difference with performance between high gain and low gain, when it comes to weather? Byrosoph— On Feb 04, 2011 I'm thinking of getting an outdoor antenna because even though I have cable, my picture comes in all fuzzy. I can't stand it, and it seems the worst on my...
The more directors a Yagi has, the greater the forward gain and the longer the antenna becomes. This type of antenna has become particularly popular for television reception, but it is also used in a number of other domestic and commercial applications where an RF antenna with high gain and ...
The gain of an antenna can be regarded as the ratio of the radiation efficiency to the total input power. It is the product of the radiation efficiency and directivity. The absolute gain is the product of maximum efficiency and the directivity. The polarization of the antenna is also a very...
Updated on 13 December 2011 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...

The Axial Ratio (AR) of an antenna is defined as the ratio between the major and minor axis of a circularly polarized antenna pattern. If an antenna has perfect circular polarization then this ratio would be 1 (0 dB). However, if the antenna has an elliptical polarization then this ratio...

Is More Antenna Gain Better? The Logarithmic dB Scale Antenna engineers use a logarithmic scale to express this apparent 2x (times two) mirror power doubling as “+3 dBi”. It still means “doubling”. Here are some other examples of ratios or multipliers on the engineering dBi gain log sca...
Antenna Gain Specs - What Do They Really Mean?1 dB. [...] if free space gain figures are given in decibels with reference to a dipole (dBd), subtracting 2.1 dB will provide the corresponding free space gain with respect to an isotropic radiator (dBi), and vice versa.Joel H Hallas...
