What is the Importance of High-Quality RF Connectors in Antennas?

As a UHF Connector Factory, share with you.

High-quality RF connectors are the cornerstone of any kind of antenna design. The RF connector in the antenna is essential for its dual function: the mechanical connection between the antenna and the RF system to which it is connected; and the conduit that serves as the flow of RF energy between the connected RF system and the antenna elements located in the radome.

RF connectors are also the most common point of failure in deploying antennas. Although some antenna designs will include additional mounting support structures and flange bases that provide additional stability, most deployed omnidirectional antennas still rely on RF connectors as their only mechanical connection points.

If you choose a cheap or poorly designed RF connector, ignoring the importance of this in the design stage may reduce the overall electrical performance of the final antenna design in an unexpected way and make the antenna susceptible to mechanical failures. These failures will not only result in the loss of communications, data or video in untimely times, but also may be life-threatening for first responders or military personnel who rely on a powerful wireless communication network to ensure their safety and mission success.

It is also important to choose the RF connector that is most compatible with the intended application of the antenna. For example, SMA RF connectors are usually very suitable for indoor or commercial RF applications, but may not be suitable for rugged outdoor military applications. For applications in extreme environments, it may be worthwhile to use an RF connector that can withstand more abuse for size trade-offs, but it takes up more space and weighs more on the face of the radio.

Factors of unstable RF connector signal

When using the connector, the pin should be opened with absolute force, but it is easier when it is separated. Therefore, it is judged that the connection of the electrical connector is more important than the separation force. Therefore, the interaction of the two forces of insertion and removal can easily cause the connector to wear out. If you want to reduce wear and tear, you can look at the following good methods: You can increase the strength of the gold plating layer on the contact surface of the connector, so that you can effectively reduce friction. The contact surface of the connector can be nickel-plated first and then gold-plated, which will cause less friction than gold plating directly on copper, which can reduce the wear of the connector.
