The Garmin Magnetic Mount Antenna connects to your Alpha handheld transmitter or Garmin 320 or 220 with a coaxial connection and the antenna mounts to the outside of your vehicle through a very powerful magnet. This magnetic mount antenna will work whether the car is moving or stationary. It is an important tracking tool when trying to relocate your hunting dog. The antenna is 12" long and increases the range and strength of the signal between your transmitter and your dog's TT10 collar.
This antenna is also compatible with the Garmin Alpha, Garmin Astro 220 or Garmin Astro 320 handheld tracking systems.
