Struggling with limited radio coverage while camping? Join me as I tackle this challenge headon by building a DIY GMRS repeater that extends the range of our family's GMRS radios. Perfect for keeping in touch over greater distances in remote areas!

In This Video, You'll Discover:

Why I Built This: Faced with connectivity issues during our camping trips, I decided to create a costeffective repeater system to ensure reliable communication.
How It Works: Learn about the components that make up this repeater, including two GMRS radios, an innovative audio crossover setup, and the crucial duplexer that manages signal direction—all housed in a portable box.
Antenna Configurations Explained: I'll go over the different antennas used, such as the Midland GMRS tuned antenna and a Jpole antenna, and why choosing the right one matters.
Field Testing Plans: Hear about my upcoming plans to fieldtest this system on our next camping adventure and how you can follow along for updates.
Build Details:

Component Insights: Get an inside look at the assembly process and the technical choices behind the duplexer and antenna setups.
Challenges & Solutions: I share the hurdles encountered during the build and the solutions that kept this project on track.
