Rigid line splice 1 5/8" SMS-2


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 Rigid line splice 1 5/8" SMS-2 enables you to transmit high-frequency signals reliably and flawlessly with optimum protection of your sensitive equipment in a power range up to 20 kW @ 100 MHz (at +40 °C ambient temperature), 13.5 kW @ 230 MHz (at +40 °C ambient temperature), 7 kW @ 860 MHz (at +40 °C ambient temperature) with maximum passive intermodulation (IM3).

The positive characteristics are briefly summarised: outer conductor system without contact ring, in copper / copper-alloy, quick and simple assembly, no special tools required, PTFE insulation, for indoor application.

A rigid coaxial line splice is part of the SPINNER SMS quick clamp system and connects the outer and inner conductor components directly. The advantage is that the customer can easily cut the rigid line to length on site, without flaring or brazing. The assembly is therefore very simple, and no special tools are required. The SMS system is provided solely for indoor installation.
