The Prostick Plus is for 1090 Mhz since it has a filter for 1090MHZ built-in.
As far as I’m aware this doesn’t work for the UAT frequencies ( but I can be mistaken). If you want to receive ADS-b and UAT you wil need 2 decoders ( 2 Prosticks for example).
Hmm why would I need a splitter? Couldn’t I just connect the antenna to the Flight Stick Plus and a Filter and antenna to the Flight Pro Stick?
Its basically what I am doing now with a RTL-SDR Blog V3,Filter and Antenna for 1090Mhz.
Planning on connecting another RTL-SDR Blog V3 to the PiAware once I figure out how to configure PiAware to enable 978.
This will be temporary till I get the FlightAware Sticks.
Certainly, if you have 2 antennas you don’t need a splitter.
I was under the impression you had one antenna ( my bad, assumption is the mother of all f*ckups)
Fot the installation of 978 Mhz folow the steps here
You need to install dump978-fa instead of dump1090-fa
You are using the SD card image for your setup.
This comes with the operating system for your Pi ( Raspbian Bullseye is the operating system on the card).
In order to get both dongles installed as well you will need to login to the Pi4 via SSH. I use the program called Putty for that.
This connects to the Raspberry Pi on port 22 giving you a command line interface where you can input the commands.
then you can execute step 1,2,3
In Putty you can put in the ip adress of the raspberry pi ( inside your network) to connect to it.
Login to the device with the username “pi” and password “flightaware”.
then you can execute the steps
