How to change the antenna?
Quote from GeoAstra Official on April 29, 2026, 2:02 pmThe Y55G device antenna is replaceable and compatible with a male SMA connector.
For example, you can replace the original Y55G antenna with the Columbus HAK-1 Helical Antenna Kit. The HAK-1 magnetic base makes it more convenient to position the antenna exactly where you want to collect positioning data.
You can purchase the HAK-1 from the link below:
