Whether crimping, cutting or soldering - our trained employees work with calm hands and great precision. As soon as it goes beyond the standard cable, we assemble cables with our in-house manufacture that specifically fit your requirements.


Since the company was founded in 1982, elspec group has been able to collect an enormous amount of knowledge in the field of Radio Frequency. Even though we offer a variety of standardized cables, we also offer customized Network Analyzer Test Cables, which we craft in our own manufactory.


Good is not good enough when it comes to the quality of our products. We know for sure our RF Cable Assemblies and quality assurance is a top priority for us. This is mirrored in our excellent products. With our state of the art machinery, for example of the companies like Schleuniger and Rohde & Schwarz, we make sure that our products are of the highest quality.

Connect coaxial cable adapter correctly (with torque wrench)

Posted by elspec group

Coaxial measurement cables must usually provide precise measurement results on the Network Analyzer. A torque wrench is essential to ensure that the lifespan of the cable is as long as possible, and that the measurements are accurate. It prevents over-twisting and thus prevents damage to the cable.
