Yes, it’s the orange one. I don’t have a Pi, just a desktop PC running a Debian Buster-based distro, dump1090-fa and the Linux Mono version of VirtualRadarServer 3.3.0-6 beta on Mono 6.12. I’m not (yet) a FlightAware feeder, I’m just tracking planes for my own enjoyment at the moment.
I hooked the cantenna back up to the original 10 meters of RG6 and plugged the dongle directly into a powered USB hub on my computer and will test for a while. So there’s a total of roughly 13.8 meters of coax, all good quality meant for satellite dishes, not the cheap cable TV stuff.
Oh well, the USB extension cable was a nice idea. I thought it might be OK if I powered it from the externally-powered hub with nothing else connected to the hub. Maybe I can get a better cable. The one I got is shielded and with a clear plastic coating. It’s probably a cheap one. Or else I’ll just stick with the RG6. I just tested with a NanoVNA and it says I’m getting a 1:1 VSWR at 1090! That was unexpected due to the impedance mismatches. I thought 1.5:1 was the best I could hope for. I wonder if the 8cm or so of RG316 I have between the RG6 and the dongle is acting as a matching bridge or something? Weird.
I have a SAW filter on the way and should get it next week. I’m sure that will help. It will go upstairs near the antenna.
