What factors should be considered when purchasing RG400 coaxial cable?

Specification requirement

You should be clear about your specification requirements before purchasing RG400 coaxial cable. RG400 coaxial cables have different sizes and characteristics, such as the diameters of internal conductors and external shields, as well as the frequency range. Make sure you know the specifications you need to meet your specific application needs.

RG400 coaxial cable

Frequency and bandwidth: determine the working frequency range and bandwidth requirements of the required RG400 coaxial cable according to the practical application. Cables with different frequencies and bandwidths are suitable for different types of signal transmission.

Length: ensure that the cable length meets the cabling or connection requirements. Cables that are too long or too short may cause signal loss or inconvenience.

Diameter: select the appropriate cable diameter according to the power and transmission distance of the cable. Thicker cables can reduce signal loss, but may not be easy to install and maintain.

Electrical characteristics: understand the electrical characteristics of the cable, including impedance, transmission loss, speed and other parameters.

Ensure that the electrical characteristics of the selected cable match the application requirements.

Outer sheath material: select the appropriate outer sheath material, such as PVC, PE or LSZH, according to the working environment and use scene. Different materials have different weather resistance and corrosion resistance.

Working temperature range: confirm whether the working temperature range of the cable meets the actual use conditions. Especially in the extreme temperature environment, the cable should work normally without being affected.

Shielding type: know the shielding type of cable, such as single-layer shielding, double-layer shielding or three-layer shielding, etc. Different shielding types affect the anti-interference performance of the cable.

Compliance: ensure that the selected RG400 coaxial cable conforms to the corresponding international or industry standards, such as MIL-C-17 standards.

Connect connectors: if you need to connect connectors, you need to know the types and specifications of cable connectors to ensure that the cable is compatible with other devices or connectors.

Metal plating: if the application requires high signal transmission quality and corrosion resistance, RG400 coaxial cable with metal plating can be selected.

Signal transmission performance

The main purpose of RG400 coaxial cable is to transmit high frequency signals, so the signal transmission performance is very important. When selecting a cable, you should pay attention to its performance indicators such as attenuation loss, impedance matching and interference suppression. Ensure that the selected cable has good signal transmission characteristics to ensure stable and reliable signal transmission for your application.

Transmission loss: understand the transmission loss of RG400 cable in the required frequency range. The lower the transmission loss, the better the signal transmission quality, especially in long-distance transmission or high-frequency applications.

Impedance matching: verify that the characteristic impedance of the RG400 cable matches the impedance of other connecting devices in the system. Impedance mismatch will lead to signal reflection and loss, affecting the quality of signal transmission.

Coherence: phase consistency and signal coherence are important in high-frequency applications. Select the cable with stable phase characteristics to ensure the accuracy and stability of signal transmission.

Anti-interference: RG400 cable should have good anti-interference performance, especially in the environment with strong electromagnetic interference, which can effectively reduce the impact of external interference on the signal.

Bandwidth: understand the bandwidth capacity of RG400 cables to ensure that they meet the signal frequency range required in practical applications.

Speed: in high-speed data transmission scenarios, we need to pay attention to the transmission speed of RG400 cable to ensure the efficiency and stability of data transmission.

Attenuation balance: measure the signal attenuation balance of RG400 cable at different frequencies. Balanced attenuation performance helps to maintain the accuracy and consistency of the signal.

Phase distortion: learn whether the RG400 cable will cause phase distortion during signal transmission. Phase distortion may cause signal distortion and affect the performance of the system.

Temperature stability: confirm whether the signal transmission performance of RG400 cable is stable under different temperature conditions. Temperature changes may affect the electrical performance of the cable.

Durability: signal transmission performance is also related to the durability and life of the cable. Choosing RG400 cables with high quality and durability can reduce the loss and trouble caused by frequent replacement.

Maintenance of RG400 coaxial cable

Considering the characteristics of RG400 coaxial cable, installation and maintenance are also factors to be considered. Make sure you understand the installation requirements for the cable, including bending radius, temperature range, and waterproof requirements. In addition, the cable is inspected and maintained regularly to ensure its normal operation and extend its service life.

Wiring planning: careful wiring planning is carried out before installing the RG400 cable. Ensure that the cable length is appropriate, avoid unnecessary bending or stretching, and reduce signal loss.

Protective measures: when passing through walls, floors or other obstacles, a suitable protective sleeve or conduit should be used to protect the cable from damage.

Stay away from interference sources: try to avoid putting RG400 cables too close to power cords or other interference sources to reduce the impact of interference on signal transmission.

Proper fixing: use suitable fixtures to fix the cable in the desired position to avoid cable loosening or vibration and ensure the stability of signal transmission.

Keep the cable clean: make sure the cable is installed neatly and avoid entanglement or crossover, which helps to maintain the service life and performance of the cable.

The select of supplier

It is important to choose a reliable supplier or brand. By selecting reputable and experienced suppliers, you can get better product quality, technical support and after-sales service. When selecting suppliers, you can refer to the comments and suggestions of other users in order to make informed decisions.

  • Reputation and reputation.

  • Product quality and certification.

  • Technical support and after-sales service.

  • Delivery and supply capacity.

  • Price and cost-effectiveness.

  • Reference and evaluation.
