SPINNER adapters offer outstanding electrical and mechanical properties

Adapters are used to connect transmission lines with of 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 52-120 BT female to 52-120 SMS adapter ensures optimal performance for signal transmission between transmitter and antenna in broadcast stations.

Outstanding RF characteristics, best possible passive intermodulation and VSWR

A 52-120 BT female to 52-120 SMS adapter enables you to reliably transmit radio-frequency signals in the frequency range from DC to 890 MHz.

The adaptor offers a transition from interface 52-120 BT female to interface 52-120 SMS. The connector has a straight direction.

With the flaring technique system (BT) the outer conductor tube is flared by using a SPINNER flaring tool. The different components are connected together with coupling elements. The electrical contact at the outer conductor is done via a metallic ring which is mounted on periphery of the insulation disc of the coupling element. The very stable connection ensures a high RF tightness and repeatable electrical length. The BT flaring technique system is provided for indoor application and is designed to handle the maximum RF power up to 860 MHz. Please take into consideration that for rigid lines inner supports are necessary depending on the wanted line length. The inner supports prevent the inner conductor from sagging.

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.
