Buying Guide

Match connector and protocol

Confirm the antenna or receiver uses the connector (SMA, USB, JST, etc.) and protocol your device or controller supports to avoid adapter needs

Consider application: marine, UAV, RTK

Choose antennas rated for your environment—marine antennas for boats, compact USB receivers for laptops, and RTK-compatible mounts for precision mower or survey setups

Check GNSS chipset and updateability

Prefer modules using modern chipsets like u‑blox NEO‑M8N for multi‑constellation support and firmware update options that improve fix reliability

Mounting and form factor matter

Confirm whether you need a pole or wall mount, adhesive base, or magnetic housing to ensure stable placement and optimal sky view

Power and interface requirements

Verify power source and interface — USB power for plug‑and‑play receivers, or voltage and wiring needs for integrated compass/GPS modules on flight controllers
