The Laird mobile coil antenna with an elastomer spring provides increased flexibility, better shape retention, and eliminates electronic noise & road noise compared to stainless steel springs. The mobile coil antennas will continue to maintain all of the features that make them unique, such as stainless steel whips, housings constructed with ABS material injection molded around a solid brass insert, and gold plated push pin contacts. Together, the mobile coil antenna / elastomer spring make Laird Technologies the obvious choice for quality and long lasting value for demanding mobile radio communications. **No metal ground plane required.
