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...

An antenna gives the wireless system three fundamental properties:gain,directionandpolarization. Gain is a measure of increase in power. Gain is the amount of increase in energy that an antenna adds to a radio frequency (RF) signal. Direction is the shape of the transmission pattern. As the g...

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...
With an offset feed, the horn is set at the bottom of the dish. That way, it can perform its duties without interfering with incoming signals, so the antenna can work to its full potential. BySushiChamp— On Jun 22, 2011 @ginSoul – I can’t stand it when TV shows do that! I ...
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...
This results in increased gain over an antenna dispersing energy in a 360-degree circle, such as the omni-directional model of other antenna designs. One disadvantage of the Yagi design is its large size, especially for the range achieved. Advertisements ...
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...
