Antenna Spec Front to Back Ratios
 

What exactly is the Front to Back Ratio and what effect if any does it have on an antenna's overall gain specs?

F/B ratio is one of the parameters that describes how the antenna behaves. Generally, the higher the gain of any given antenna, the higher the F/B ratio. There's more to it, but that's a very simplified explanation.

In a TV antenna the front to back ratio does not matter unless there is interference or reflections that arrive at the antenna from the back side. Antenna gain is more defined by the width of the pattern off the front of the antenna.
