Long Range Mag Mount Garmin Whip Antenna
Buzzard's Roost Long Range Magnectic Antenna for your Garmin Astro 220, 320, 430 or Alpha. This antenna will out perform the Garmin Magmount. Ranges will vary depending on terrain and conditions. I have personally seen 8 miles here in Eastern NC but average is 2-4 miles in average hunting conditions. Comes with 20' coax.
