If you have a VHF Radio in your truck with an antenna for your radio, you should keep one of these Garmin adapters in your truck.

This is a simple adapter that allows you to connect your Garmin® Astro, or Garmin® Alpha receiver to your radio's antenna. It's very simple to use and we recommend you keep one of these products in your vehicles glove compartment should you run into a situation that you need to increase your range.
