Kerberos SDR 70cm Array

This is a suction-cup mounted antenna array (for 70cm band) for use with the KerberosSDR coherent receiver system. It has an inverted airfoil design to keep it on the vehicle and has been tested over many months at high-speed while installed onto a glass roof.

Prints well and holds up well with PLA but may want to consider PETG or ABS for high temperature operation.

Assembly is pretty straightforward. The parts list is included.

Adhesive copper disks can be cut out using a hobby vinyl cutter. They are required if using small helical rubber ducky antennas.

KSDR will easily track a 5W 70cm transmitter from 3 miles away using the small antennas. Bigger antennas will work well but might affect the structure at higher speeds.

The wire loom is useful for keeping the wiring organized. If it does not snap together well, then use 2 small zipties to keep it closed.

The SMA holder is useful for creating a quick disconnect for when calibrati
