Know before you buy
Yes. By providing a clearer line of sight to satellites, this antenna significantly improves signal reception in environments where your internal GPS might struggle, such as deep canyons or heavy tree cover.
Absolutely. The antenna is built with a rugged, water-resistant housing specifically designed to withstand the vibrations and environmental challenges common in off-road and race vehicle applications.
The antenna comes with a 9.8-foot (3-meter) cable. While this is sufficient for most vehicle installations, we do not recommend adding extensions, as signal loss can occur over longer cable runs.
The antenna is designed for a surface mount. It includes all necessary mounting hardware and a sealing gasket to ensure a secure, weather-tight fit on your vehicle's exterior.
This antenna is compatible with most Garmin Tread Edition devices that feature an external GNSS connector. We recommend checking your specific Tread model's manual or the compatibility list on the product page to confirm the connector type matches.
