What are the characteristics of a car antenna? What are the precautions for use?

When it comes to vehicle-mounted antennas, I believe many of my friends are familiar with them, because there are too many private cars now, and we have many opportunities to come into contact with vehicles. We may have heard about them, but not many friends may really understand them. Next, let’s talk about the characteristics of vehicle-mounted antennas and related usage precautions.

1. Characteristics of vehicle antennas

1. Characteristics related to vehicle structure:

The length of the single-axis antenna should be one-quarter of the wavelength of the radio wave received, but the wireless length that can be installed in the car is only about 1 meter.

2. Characteristics related to the use environment:

Due to the needs of freely moving cars, vehicle-mounted antennas are generally non-directional antennas. What is currently being promoted is the improvement of radio and TV receivers. The properties that vehicle-mounted antennas must meet include water resistance, earthquake resistance, corrosion resistance, etc. At the same time, its safety and impact on the shape of the entire vehicle must also be considered.

3. Features related to multimedia:

To ensure that the vehicle-mounted antenna is not interfered by other antennas, ensure its relevant acceptance performance, ensure the feasibility of the installation and commerciality in appearance, etc., multiple antennas can be installed in limited locations.

2. Relevant usage precautions

1. Pay attention to the vehicle body to be grounded;

2. Consider the noise aspect;

3. Related waterproofing and drainage should be considered;

4. Pay attention to wind noise.
