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.

Testing standard

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
