Antenna Springs & Assemblies

Military Antenna Springs

Antenna springs also referred to as whip antenna springs, are used at the base of a vehicle antenna to ensure stability and support of the antenna mechanism. MW Components produces a variety of antenna springs, many of which are barrel springs, spanning multiple sizes and finish options. We work with you to determine the correct spring for your application to ensure the best fit.

Antenna springs are formed with metal tangs on the end which allows for locking into the metal base of a vehicle. Improper locking due to antenna spring malformation can lead to antenna breakage. To ensure the highest quality antenna springs with the longest possible cycle life, we perform rigorous in-house testing for torque, tension, and whip. MW Components’ antenna springs are developed to withstand harsh environmental conditions, particularly military applications.

Custom Antenna Springs

The majority of the antenna springs we produce are made with stainless steel and finished with a black oxide coating which provides light reflection, rust prevention, and adds durability to the part. However, we are a custom spring manufacturer, meaning we work with your teams to develop the correct part for your specific application. This could include any number of finishes, certifications, etc.

We even offer design and engineering assistance from industry experts at no cost to you. We also have a vast repository of wire thicknesses and machining capabilities across multiple manufacturing facilities, ensuring that whatever you require for your custom antenna springs and assemblies, we can produce them.

Antenna Springs Manufacturing

Our antenna springs are produced to withstand harsh environments and are built to last due to our propriety production process which includes advanced CNC machining. In addition to state-of-the-art manufacturing, all antenna springs undergo rigorous testing for durability and cycle life, including a whip test, bend rate, flex test, and initial tension test. This ensures only the highest quality parts are used in your assemblies. We also offer a variety of optional certifications to comply with industry standards and further ensure the performance of your parts.

We are a custom spring manufacturer and a custom component manufacturer with multiple facilities, giving you access to a wide variety of size ranges, materials, finishes, and customization options. Since our production capabilities extend beyond springs, we are able to perform end-to-end production on spring assemblies, ensuring that each and every component within those assemblies functions perfectly as intended.
