Outdoor Dog Supply’s Super Extendable/Foldable Antenna for Garmin Alpha and Garmin Astro Handhelds

Best handheld antenna for Garmin Alpha 100, Garmin Astro 320 and 220 handhelds

Maximize your tracking range with this long range extended super tracking antenna.  This antenna is for Garmin Alpha and Astro 320 and 220 handhelds. This antenna tracks superior to any of the stock antennas you get with the Astro or Alpha GPS dog tracking systems and will fold down and fit comfortably in your pocket or on your side. This is one of the most durable foldable-extendable combo antennas on the market for Garmin GPS products.  Our local hound hunters love this antenna and it is a personal favorite of ours.  This antenna tracks as well if not better than the Garmin Mag Mount Antenna and our Mini Mag Antenna.

Anyone who use to run quick track knows what a quick connect is: the 1/2 turn on or 1/2 turn off, no more screwing and unscrewing the antenna off.  This also saves wear and tear on the normal antenna connect on your handheld. This super extendable antenna connects only via the quick connect base attachment.


For your convenience, we have added the option of a 2 pc or 3 pc quick connect kit at a reduced price with this antenna, for our customers that currently do not have on of Outdoor Dog Supply’s quick connect kits.

Compatible with the Garmin Alpha 100, Garmin Astro 430, Garmin Astro 320, and Garmin Astro 220.

    I have tested and used over 20 antennas trying to find that perfect combination of durability, long range tracking, and compact collapsible ability. This is it. The only neg is this only works with outdoor dog supply’s quick connect base. For the hound guy or gal that stays away from the truck but still likes to keep track of his dogs miles from him, this is the antenna for you.

    Best antenna I have ever had alot more durable then and folding antenna I have had and picks up great! I still have communication at 600-700 yards with it folded down to the side and when you do lose them just fold it up and it picks them up as your folding it up! I recommend it to anyone! And I received it about 3-4 days after I placed my order! Will deffinately continue dealing with Outdoor Dog Supply!

    This antenna works great. Extends the range of my alpha. But the threads on the lower connection are too weak an come loose easy.

    Good product. It was recommended by a friend and has proven very useful when I need to track dogs at longer distances while away from my truck. Gives me a great head start on my dogs location before I reach the truck. The only negative I have found is that the antenna broke on me at the “knuckle” where it attaches to the base, totally my fault. Just make sure you always slip the sleeve down over the folding mechanism and you should not have any problems at all. Thanks Outdoor Dog Supply for your excellent products and superior service!
