Antenna gain is a measure of how much power is radiated in a particular direction by an antenna compared to a hypothetical isotropic radiator (an antenna that radiates equally in all directions). Antenna gain is usually expressed in decibels relative to an isotropic radiator (dBi) or a dipole radiator (dBd).

The FM radio transmitter is composed of different signal equipment, mainly composed of high-frequency equipment, low-frequency equipment, and power supply equipment. High-frequency equipment and low-frequency equipment cooperate with each other to complete signal transmission and amplification in an orderly manner.
Radio amateurs, or hams, are not so much a special group as they are a collection of several different special groups.
