N6NA 2 meter repeater coverage

This N6NA 2 meter repeater transmitter coverage map shows estimated field strengths to an isotropic antenna 10 feet above ground based on the N6NA repeater 800 watt effective radiated transmitter power, 2000' ASL antenna elevation and terrain topography.

The 145.25 MHz repeater transmitter is located east of Sacramento in the foothills near Shingle Springs at about 2,000 feet. Our 800 watt effective radiated power system is designed to provide wide area coverage to the greater Sacramento area including Woodland, Davis, Elk Grove and beyond.  This repeater's coverage typically extends into the Sacramento and San Joaquin Valleys past Chico, CA to the north, past Modesto, CA to the south and to the west past Concord, CA.  Your range will vary depending on your radio and antenna.

In emergencies, the N6NA 145.25 MHz repeater system is the designated Tactical and/or Resource Net Frequency for the Sacramento Amateur Radio Communications Reserve (ARES/RACES).

The 2 meter system uses several remote receivers located around the Sacramento area that are connected to a "voter" which selects the best signal and sends it to the repeater transmitter. This facilitates repeater access with weak signals such as from low power handheld radios.
