Yagi Antenna Gain at Michael Doxey blog

Yagi Antenna Gain. The directional forward gain and “front to back” ratio (f/b ratio) features are hallmarks of the yagi and the reasons for its high popularity. The yagi antenna is a directional antenna using parasitic director and reflector elements to amplify the radio frequency signals from the direction it is pointing. It is simple to construct and has a high gain, typically greater than 10 db. This is simply a ratio of the antenna radiation in the forward direction of the antenna and the reverse direction of the antenna, often expressed in a log ratio (db). The gain can be increased (and the pattern made more directional) by adding more directors or optimizing spacing (or rarely, adding another reflector). The yagi has high gain in one specific compass (azimuth) direction and very low gain in the opposite direction when compared to the classic 1/2 wave dipole. The antenna's radiation pattern or polar plot as it is sometimes called plays a major role in the overall performance of the yagi antenna.
