Opera Cake is an antenna and filter 'router' for HackRF, allowing you to switch automatically (via frequency or time) or manually via the command line.
While it can be used independently, the killer feature of Opera Cake is its automatic antenna routing when used with HackRF.
Without any modifications to the SDR software, it automatically routes the output to specific antennas, filters, amplifiers, etc.
It is also compatible with the HackRF One spectrum analyzer. The hackrf_sweep command can automatically scan multiple antennas.
UP TO 8 AUTOMATICALLY SWITCHED ANTENNAS
Connect HackRF One to multiple antennas, with automatic switching based on frequency or time. Set up once and never play around with your antenna setup again.
UP TO 4X FILTERS
Opera Cake also works in 4x Filter Bank mode, allowing you to automatically route your stream through selected filters without having to reconnect your hardware every time.
