Protection cap for 4.3-10 female


Protection cap for 4.3-10 female provides mechanical protection and thus secures optimum radio-frequency transmission performance

Your entire high-frequency connection is only as good as its individual connecting elements. RF ports are critical elements in this respect, because they can be damaged quickly, e.g. by impacts during transport, installation or by weather influences such as water and dust. This results in a poorer quality of the RF connection and a shortened life expectancy of the damaged ports. If you also have (temporarily) open ports or often open and close RF connections, you can protect your connections with the Protection cap for 4.3-10 female.

All our protective caps have an internal or external thread and correspond to the degree of protection IP 68, which means that they are absolutely dustproof and waterproof. The use of the Protection cap for 4.3-10 female thus significantly reduces costs by effectively protecting your RF components while ensuring a constant quality of the RF connection. Our robust protective cap is made of the following material: copper-alloy / nickel-plated.

The 4.3-10 connector system was designed to meet the latest requirements in mobile communication in terms of size, robustness, performance, and other parameters. Its small footprint supports the use of smaller components, mitigates risks if equipment is assembled without due care, and delivers outstanding electrical performance.

The Protection cap for 4.3-10 female is suitable for connections such as those used in mobile radio for antenna base stations and in-building distributed antenna systems. In addition, there are further applications in broadcasting, or especially in test laboratories and measurement environments. SPINNER applies extremely high standards with regard to quality, engineering, materials, and manufacturing. This enables us to offer protective components with the best possible performance while ensuring optimized installation and failure-free operation, under even the harshest conditions.
