README.mdMatrix Antenna Switch
This is a 6x2 antenna switch which allows to connect two TRXes to up to 6 antennas. The device currently consists of two boards: tha main switchong board and an add-on coomunications module. The communications module allows the switch to be controlled remotely via RS-485.
Parameters
The switch provides decent isolation between the 2 TRX ports. - better than 75dB below 10MHz - better than 65db below 30MHz - better than 50dB below 50MHz
Control Software
A python app that provides a WebUI to control the switch is provided. The app reqiures that a serial-to-RS485 or USB-to-RS485 converter is connected to the machine it is running on (in our set up this is usually a Raspberry Pi somewhere in the shack floor ;) )
