SPINNER Rigid Coaxial Lines components - robust performance

A rigid coaxial transmission line is mainly used in broadcast systems to transmit radio frequency signals between transmitter and combiners as well as between combiners and the antenna. The advantage of rigid coaxial lines is that the radiation leakage and attenuation, especially at higher frequencies, is lower than with flexible coaxial cables. This means that greater power can be transmitted, and higher shielding attenuation can be achieved.

The protection class is IP 40.

The positive characteristics are briefly summarised: for lengthwise adjustment and bending, with fixed coupling elements on both sides.

Coaxial flange connectors, generally known as “EIA flanges”, are connected by a coupling element. The flange connector system complies with international standards EIA STD RS-225, 339 IEC, DIN EN 122150 and MIL-F 24044. The EIA flange connectors are excellently qualified suited for pressurized systems and for outdoor installations. 6 1/8" EIA connectors are used to link two elements of a rigid or semi-rigid high performance coaxial transmission line for radio frequency signals. Typically, these are operated in systems for very high power transmission (from kW to MW), e.g. in DAB, DVB or FM broadcast systems or in high-energy applications in research facilities (particle accelerator, plasmatron).

A rigid coaxial line straight section comprises all components for rf signal transmission including inner and outer conductor, flanges and coupling element and provides a complete electrical interface.
