47 inch Telescopic Antenna that folds down and allows your Garmin Astro or alpha to be carried safely in most carry cases or for easy fit in your pocket. This super long range antenna screws directly into the Garmin handheld. It will add range to your Garmin handheld dog tracking system when you need the extra range to track your dogs. Just extend the 47 " telescoping part of the antenna and it should add at least 55% or more range. Some users have found it doubles their range, but all systems are different and the position of the satellite and the terrain will have a bearing on your results.
