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.

Outstanding RF characteristics, best possible passive intermodulation and VSWR

The Trimming line 1 5/8" EIA 470-860 Mhz 7 kW indoor 5 trimming screws enables you to transmit high-frequency signals reliably and flawlessly with optimum protection of your sensitive equipment in a power range up to 7 kW @ 860 MHz (at +40 °C ambient temperature) with maximum passive intermodulation (IM3).

It supports the use of the following frequency bands : Band 4/5

The positive characteristics are briefly summarised: used to improve the VSWR, with 5 trimming screws, for indoor application.

A rigid coaxial trimming line allows precise adjustments to the transmission line’s electrical length. By trimming or adjusting the length, engineers can fine-tune the impedance matching, phase, and other parameters. The trimming line connect to flanges and coupling elements.
