Here is the final(?) version (Version 2) of my portable ADSB receiver. The main design criteria was it had to be smallish and reasonably easy to deploy. Version 1 had a DVB-T dongle, I’ve recently upgraded it to the ProStick & Filter combo with quite pleasing results in terms of range increase.
Its powered by a TP-Link POE injector and hooks up to a TP-Link pocket router/WAP & 4G/LTE USB modem combo so it can get time sync and I can access it via wifi on my laptop or iPad.
I have a longer piece of conduit and coax if I want to get the antenna a bit higher.
