Garmin developed this portable handheld long range antenna especially for the Garmin Astro GPS Dog Tracking system and it's designed to increase the range of the hunter's handheld 220 receiver. When a dog travels out of range, the long range antenna can be lengthened to 3 feet and attached directly to the Astro 220 via a 3 foot coaxial cable.
This new handheld long range antenna is perfect for the big running bird dogs and hounds. Plus it gets better range even when closed than the standard antenna. When you need more range, all you do is extend the antenna out to a maximum of 3 feet.
The handheld long range antenna features a molded handle and lanyard; and only measures a 1/4 meter long when stored so it can be easily carried in a hunting vest.
