Video: HackRF Jawbreaker SDR antenna mod


If you were fortunate enough to score one of the HackRF Jawbreaker SDR boards from Michael Ossmann, you may have noticed the board has an SMA antenna connector as well as a built-in PCB antenna (intended for operation near 900 MHz). Ossmann recommends that you disable the on-board PCB antenna if you intend to use the board with an external antenna.

In this short video, HackRF co-developer Jared Boone demonstrates how to carefully make the necessary mod to the board, which entails carefully removing R44 and cutting the underlying trace.
