What is antenna Front to Back Ratio?
Answer:
The Front-to-Back Ratio is a parameter used in describing directional radiation patterns for antennas. If an antenna has a unique maximum direction, the front-to-back ratio is the ratio of the gain in the maximum direction to that in the opposite direction (180 degrees from the specified maximum direction). This parameter is usually given in dB.The true ratio often varies dramatically from channel to channel.(Of course, if you have the radiation pattern then you don’t need the F/B number.)
