Garmin Original Extended Range Antenna for Alpha and Astro Handhelds

Extended-range antennas replace or augment the standard VHF antenna on your Garmin Alpha/Astro handheld to increase tracking range and signal reception, which helps keep tabs on your dogs farther out than stock antennas typically allow. Most of these extended-range antennas fit Garmin Alpha 10, Alpha 100/200/300 series and Astro 220/320/430 handhelds — just check the model fit on the individual product details to be sure.
