Sealing concepts for coaxial connectors
The electrical connecting points in coaxial connectors must be protected against ambient influences. Dust and water or moisture are a constant hazard especially in outdoor applications, e.g. mobile radio masts. Moisture, particularly, which penetrates a coaxial system, changes the HF transmission enormously and leads to impedances or poor return loss values. Seals must be fitted at all connecting points to protect the sensitive and expensive electronics. This two-part newsletter presents the requirements for correct sealing design and different sealing concepts.
