Here’s a blast from the past. Five or six years ago Habamps were very popular with FlightAware users. I used one with my home brew antenna. At the time I powered it through the coax cable.
I want to use it now, I need to use a power adapter. Can anyone identify the power connector type? None of my power adapters fit this connector. The center pin is too thick. It looks to be about 2mm. Here’s a picture to refresh your memory. Thanks!
