Total estimated cost: $30-100 depending on equipment quality and what you already have.
Pro tip: Models with TCXO (temperature compensated oscillator) offer better stability.
Pro tip: For beginners, the stock antenna that comes with many RTL-SDR kits will work to get started.
Pro tip: A Raspberry Pi makes for an ideal 24/7 dedicated receiver.
A low-loss coaxial cable to position your antenna higher or further from your computer.
Recommended: RG-58 for shorter runs, RG-8X for longer distances.
Improves reception in areas with strong interfering signals.
Recommended: Only needed in urban areas or near broadcast towers.
New to SDR? Many vendors offer complete kits with everything you need to get started:
Easy setup with pre-built binaries. Perfect for newcomers to AIS reception.
Install on Ubuntu, Debian, or Raspberry Pi OS for 24/7 dedicated AIS monitoring.
Turn your Raspberry Pi into a dedicated AIS receiver with our one-line installer.
Advanced users can build AIS-catcher from source code for maximum flexibility and performance tuning.
Source Build InstructionsRun AIS-catcher in a containerized environment for easy deployment and management.
Docker Setup GuideMore expensive SDR devices or antennas don't necessarily pay off. Location and height matter more than equipment cost. Basic RTL-SDR dongles perform very well for AIS reception.
