FCC Technician Exam Question Of The Day (T9A11)

Q) What is meant by the gain of an antenna?

A) The increase in signal strength in a specified direction when compared to a reference antenna

NJ2X Notes:
Gain is often expressed in decibels (dB).  A theoretical antenna called an isotropic radiator is sometimes used as a reference.  An isotropic radiator is a point source located in free space and radiating equally in all directions.
