The Garmin Long Range Handheld Antenna is designed for the Garmin Alpha and Garmin Astro handhelds to increase the effective GPS tracking range. When yours dogs are in close the antenna can be collapsed down to 10.5" and when needed extended to 42" for increased range. The antenna is connected to your Garmin handheld device via a 1 meter long coaxial cable.
The antenna features a molded handle and lanyard and measures just 10.5" long when stored -- small enough to be carried in a hunting vest when not in use.
