Buying Guide

Match antenna to device

Confirm connector type and explicit compatibility with your GPS unit or controller, such as Garmin, APM/PX4, Segway Navimow, or USB hosts

Choose form factor for the use case

Select marine puck, USB dongle, collar-style, or pole/wall mounts depending on installation—boats, PCs, pets, mowers, or drones each need different shapes

Look for GNSS chipset or antenna tech

Prefer devices that reference known chipsets (NEO-M8N) or RTK-capable designs when you need higher positioning accuracy

Check cabling and connectors

Verify cable length, connector type (USB, coax, JST, SMA, etc.), and whether an extension kit is required for your installation

Prioritize mounting and environmental fit

Choose water-resistant marine assemblies for boats, rugged collars for pets, and stable pole/wall mounts for robot mowers or rooftop installs

Consider integration vs. standalone

USB receivers are plug-and-play for computers, while puck-style antennas or modules often require a compatible receiver or flight controller
