SPINNER adapters offer outstanding electrical and mechanical properties

Adapters are used to connect transmission lines with different interface sizes (so-called inter-type or between-lines adapter) or within one size but different interface genders (so-called within-type or in-line adapter).

SPINNER high frequency adapters are optimized for quality and performance and are designed for the lowest possible reflection factors. The outstanding electrical and mechanical properties, the simple installation and the high reliability make SPINNER high-frequency adapters one of the most efficient and cost-effective transition connectors on the market. Precision adaptors with RF quality grade 0 are available upon request.

The SPINNER 3 1/8" SMS inner to 3 1/8" MYAT cutback adapter ensures optimal performance for signal transmission between transmitter and antenna in broadcast stations.

Outstanding RF characteristics, best possible passive intermodulation and VSWR

A 3 1/8" SMS inner to 3 1/8" MYAT cutback adapter enables you to reliably transmit radio-frequency signals in the frequency range from DC to 860 MHz.

The adaptor offers a transition from interface 3 1/8" SMS inner to interface 3 1/8" MYAT cutback. The connector has a straight direction.

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.

MYAT connectors are a proprietary development of MYAT Inc. for their coaxial rigid conductor system.
