These long range antennas are super heavy duty and increase range! Made to outlast the original Garmin antennas they are easy to install and will increase signal! We offer a 24" and a 21" antenna that work with the Garmin TT15, TT10, T5, Mini TT15, Mini T5, and DC50 dog tracking GPS collars. In our tests they both showed significant improvement with range - the 24" tracks a bit further. Made here in the USA by Outdoor Dog Supply!

Haven't used at extreme ranges but quality made and seems to keep a strong signal.

Stand up better on the collar. don't flop over like other antennas. Seem to stay connected with handheld better.
