The antenna can be divided into three categories according to the
different occasions of use: handheld station antenna, vehicle
antenna and base antenna.
Hand-held station antenna: is the personal use of hand-held
walkie-talkie antenna, common rubber antenna and pull rod antenna
two categories.
Vehicle antenna: refers to the original design installed on the
vehicle communication antenna, the most common application is the
most common sucker antenna. The vehicle antenna structure also has
a shortened type, a quarter wavelength, middle inductive type, five
eighth wavelength, double half wavelength and other forms of
antenna.
Base station antenna: plays a very key role in the whole
communication system, especially the communication station as the
communication hub. Common base station antennas include FRP high
gain antenna, four-ring array antenna (eight-ring array antenna),
directional antenna.

1. Radiation Emission
It spreads through space. From 30Mhz to 1Ghz. The interference at
high frequency is mostly radiation interference. Often, both
disturbances can coexist.
2. Conduction interference (right Emission)
Conducted interference propagates through power lines, signal lines
and other conductors. FCC requires frequency from 150Khz to 30Mhz,
and most interference at low frequencies is conducted interference.
Mainly for electrical products that work with the grid connection.
3. Antenna end harassment.
Mainly for devices with external antennas. Such as TV
FCC Certification test standards: FCC PART 15, FCC PART 18
