Sn0ren Tests the HackRF Pro Portapack H4M Pro

Over on YouTube, RF enthusiast sn0ren has posted a video reviewing the new 'HackRF Pro Portapack H4M Pro'. The HackRF Pro is the latest official version of the popular HackRF software-defined radio. It started shipping to customers back in January 2026, and it includes improvements such as improved noise figure measurements, a USB-C port, increased frequency limits, a TCXO, and an improved, flatter frequency response.

The Portapack H4M is currently the most recommended portapack product for the HackRF. A Portapack is a separate PCB board that piggybacks on a HackRF board and turns the HackRF into a portable device that can receive and transmit various signals in the field.

In the video, sn0ren starts by showing a performance comparison between the HackRF and HackRF Pro, noting increased signal strength with the HackRF Pro. The Portapack H4M Pro appears to mostly be a change in order to fit the new HackRF Pro PCB layout, but there are some minor improvements that sn0ren finds in the video, such as better buttons, a slightly larger case, a removable battery lid, metal screws, and a lanyard hole.
