29.5-68 USL-D to 7-16 female precision adapter


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 29.5-68 USL-D to 7-16 female precision adapter ensures optimal performance for signal transmission between transmitter and antenna in broadcast stations.

Outstanding RF characteristics, best possible passive intermodulation and VSWR

A 29.5-68 USL-D to 7-16 female precision adapter enables you to reliably transmit radio-frequency signals.

The adaptor offers a transition from interface 29.5-68 USL-D to interface 7-16 female. The connector has a straight direction.

The 7-16 connector has become the most widely used coaxial connection system for mobile communication systems, due to its excellent mechanical and electrical properties. In order to achieve the industry leading intermodulation performance SPINNER applies silver-plating on all inner and outer conductor parts of the standard connector. As a supporting measure, we use exclusively non-magnetic materials, and we have minimized the number of RF contact points. The connection is especially suited for transmitting medium or high power indoors and outdoors.
