Garmin Extended Range Replacement Handheld Antenna (010-10856-30)

Extend your tracking range by up to 9 miles with the Garmin Extended Range Replacement Handheld Antenna (010-10856-30). This 13-inch flexible VHF antenna replaces the standard antenna on your Garmin handheld, giving you significantly more reach when your dogs run deep into rough terrain, thick timber, or open country.

The antenna is a genuine Garmin factory replacement — not aftermarket — so it fits securely and maintains full signal integrity. It threads directly onto the SMA connector on your compatible handheld with no tools or adapters required. The flexible rubber construction resists snapping from brush or accidental impacts in the field.

Compatible with the Garmin Alpha 300 Series, Alpha 200 Series, Alpha 100, Alpha 10, Astro 430, Astro 320, and Dogtra Pathfinder Series handhelds. If you run dogs in big country or hilly terrain where the standard antenna falls short, this is the single easiest upgrade you can make.

Backed by Garmin’s warranty and CSO’s expert product support. 0% financing available — no credit needed.
