A 38cm Antenna for Compatible Garmin Tracking Handhelds

The ABBREE GPS-771 is a 38cm whip antenna with an SMA-Male connector, listed for selected Garmin Alpha and Astro tracking handhelds. Choose black or orange to suit your tracking setup.

Before your next outing, check the antenna connection on your handheld and fit the whip gently. Its 38cm profile gives you an alternative antenna configuration for your compatible tracking device without promising a fixed increase in tracking distance.

Check your exact model, regional version, operating band and connector fit. A matching SMA connector alone does not establish compatibility. This antenna is listed for the named tracking handhelds, not as a universal ham-radio antenna or a replacement for every GPS satellite antenna.

Installation and Performance

Follow your handheld's antenna instructions and do not force or overtighten the connector. Tracking reception and distance depend on terrain, vegetation, equipment and antenna placement. Improved reception in heavily covered areas is not guaranteed.

Temperature limits and a verified water-protection rating are not specified here. Confirm the environmental requirements for your intended use rather than assuming all-weather protection.
