Help Choosing the Right Power Supply for Your Mobile Radio Rig
At TekShack we guide you through selecting the right power supply for your mobile radio rig—whether you're running a CB radio antenna, GMRS frequencies, or building a full “electron dash math playground” station at home. The right 13.8V or 12V DC supply ensures your radio gear runs clean, safe, and without unwanted interference or voltage sag.
Our experts help you match radio current draw, choose between linear vs switching supplies, and make sure your installation supports your rig’s transmit & receive needs. You’ll avoid issues with noise, overheated supplies or unstable voltage that can degrade your radio’s performance or affect your CB radio antenna system.
From compact home-bench rigs to full vehicle dash installs, we’ll show you power supplies with the proper amp rating, clean output, and protective features. Browse our recommended models, then let us help with questions and installation guidance. Get your mobile rig powered right and ready to transmit.
Recommended Power Supply Models
- 50A switching, 13.8V output, high reliability for base station or multi-radio setups.
- Adjustable 5-15V, up to 30A output, noise-offset control for sensitive radio installs.
- 12A continuous, 13.8V output, trusted linear type for clean power in mobile/home rigs.

FAQs About Choosing a Power Supply
How many amps does my mobile radio rig need?
Check your radio’s specification for transmit current at full power. Then choose a supply that provides some overhead. For example many users of mobile rigs aim for a supply rated ~10 A more than the radio’s draw.
Should I use a linear or switching power supply?
Linear supplies produce less electrical noise but are larger/heavier and less efficient. Switching supplies are more compact and efficient but can introduce RF noise unless properly filtered.
What output voltage should the power supply provide?
Most mobile radio gear expects ~13.8 V DC (regulated) for home-use or vehicle battery equivalent. Ensure the supply closely matches the recommended voltage.
