Garmin Roof Magnetic Mount Antenna for Alpha and Astro

The Garmin Magnetic Mount Antenna is an external VHF tracking antenna designed specifically for use with Garmin dog-tracking handheld units such as Alpha and Astro models. It magnetically attaches to the roof or other metal surface of a vehicle, giving your handheld a stronger, elevated signal path to improve tracking performance while on the move. This antenna extends approximately 17 inches long and significantly enhances range and signal strength — especially useful when tracking dogs over open terrain, in forests, or during long hunts.

• Designed for Garmin Alpha & Astro: Works with a wide range of handhelds (including Alpha and Astro series) to boost tracking capability.

• Magnetic Roof Mount: Easy, no-tools installation on any metal vehicle surface for convenient use on the go.

• Improved Tracking Performance: Provides stronger reception and extended tracking range compared to the handheld’s stock antenna, helping maintain connection with your dog’s collar even while driving.

• Compact & Durable: Built to withstand outdoor use and frequent mounting/dismounting without compromising signal performance.
