Hybrid coupler boards for circular polarization
This repo consists of different boards that use different devices to get circular polarized antennas.
All the PCB boards have a version that where you can use SMA connectors or soldered wires. If you want to use the SMA connector boards, you will need to buy:
You must connect them correctly! Each port has to be a "dipole". Depending on their orientation you will get RHCP or LHCP.
