SRH 789 antenna modification
The Portapack (in my case, the H1) ist a great addition to the hackrf one. After I had damaged two hackrfs, my current setup now uses the version with a modified RF-frontend by Clifford Heath. This now works safely alongside my ham radio gear.

|Not the original SRH789
|No RF will pass this
|M4 fits just fine. The copper wire can be removed
|With a sharp pull, the center pin of the SMA connector comes loose
