Rigid line 90° elbow 52-120 SMS


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 90° elbow 52-120 SMS enables you to transmit high-frequency signals reliably and flawlessly with optimum protection of your sensitive equipment in a power range up to 140 kW @ 100 MHz (at +40 °C ambient temperature), 92 kW @ 230 MHz (at +40 °C ambient temperature), 47 kW @ 860 MHz (at +40 °C ambient temperature) 1) with maximum passive intermodulation (IM3).

It supports the use of the following frequency bands : Band 1, Band 2, Band 3, Band 4/5

The positive characteristics are briefly summarised: outer conductor system aluminum / aluminum-alloy, quick and simple assembly, no special tools required, PTFE insulation, for indoor application.

The SPINNER quick clamp system called SMS is based on the international rigid line standards like EIA STD RS 225, 339 IEC and DIN EN 122150. The different parts are connected by coupling elements and fixed together with clamps. The advantage of the SMS system 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.

Further remarks

• outer conductor system aluminum / aluminum-alloy
• quick and simple assembly
• no special tools required
• PTFE insulation
• for indoor application
also 57.0 kW @ 860 MHz possible, in this case it is necessary to paint the rigid line with a black, heat resistant varnish
