N6NA 145.25 MHz Repeater Coverage Map
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 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.
