Hunter Spring


The STACER® is the original antenna spring and was developed by Hunter Spring engineers back in the 60’s.

This antenna spring can be used for a wide range of applications and its unique features has long proved its worth in demanding aerospace and military projects.

When deployed, the STACER® extends rapidly under its own power into a full length, self-supporting tube that can range up to 35 feet in length.

Its unique capacity for extension, with no external force required, contributed to the STACERs success in a wide range of unique, remote deployment applications ranging from outer space to deep sea environments.
