MRC240 cable attenuation calculator

The Nm connectors we use are twisted-soldered, (resistant to water pressure up to 6 bar - recommended for connecting antennas outdoors), and standard crimp connectors, recommended for indoor installation.

Our design capability is the foundation of our business, which guarantees commitment to service and quality. By purchasing an Interline connector, you do it knowing that it has undergone a rigorous development process, and a solid construction will provide the reliable and long-lasting performance you need.

Thanks to 32 years of experience in the field of RF connectors and the market, we are experts in the production and supply of connectors and cable production. Cables can be equipped with measurement documentation, including VSWR data, losses for each connector. Our experienced internal team can provide not only a wide range of standard products for connector connectors, but also the support needed to solve all problems related to radio communication.

At Interline we provide comprehensive services that meet all the needs related to RF links. From initial problem solving, through design concepts and prototyping, to the delivery of a fully qualified production part, Interline can do anything.

In professional radio communication, design your antenna system

The attenuation of the cable between the device and the antenna does not exceed 2 dB!


The connectors on the outside must be of the "Clamp" type. Connections of this type have silicone gaskets and are waterproof.

Interline offers such connectors and internal (male N, female N, SMA, RP-SMA, RP-TNC, terminal N, R-BNC)



Comparison of Type N Antenna Connectors: Crimp vs Screw-on


In the world of antenna technology, choosing the right connector can significantly affect the performance and durability of the installation.

Type N connectors are a popular choice due to their robustness and effectiveness in signal transmission for radio communication applications.

There are two main types of Type N connectors: crimp and screw-on, which differ in design, cost, and application.


Type N Crimp Connector


The Type N crimp connector is a simpler and cheaper solution, often chosen for indoor antenna installations.

Its installation does not require specialized tools and is relatively quick, making it an attractive choice for amateurs and in fast-paced industrial applications.



- Cost: They are significantly cheaper compared to screw-on connectors.

- Ease of installation: They do not require the use of special tools for installation.



- Lack of waterproofing:

   Their design does not provide protection against moisture,

    which can be problematic in humid or outdoor environments.

- Limited protection against external elements:

   There is no possibility of additional protection, such as by wrapping with vulcanizing tape.


Type N Screw-on Connector


Although more expensive and requiring more effort during installation, the Type N screw-on connector offers much better protection against external factors.

It includes a rubber gasket that provides waterproofing, and its design allows for additional protection by wrapping with self-vulcanizing tape.



- Waterproof: The rubber gasket effectively protects the connection from moisture.

- Additional protection: The possibility of securing with self-vulcanizing tape increases the durability of the installation.

- Outdoor use: Ideal for outdoor use in various environmental conditions.



- Cost: They are more expensive than crimp connectors.

- Complex installation: They require specialized tools and more time for installation.




The choice between a crimp and a screw-on Type N connector depends on the specifics of the project and the environmental conditions in which it will be used. For indoor, dry places, a crimp connector may be sufficient and more cost-effective. However, for outdoor applications or in places exposed to moisture, the screw-on connector offers better protection and durability, albeit at higher initial and installation costs. Choosing the right type of connector can significantly impact the long-term reliability of the entire antenna installation.
