Last week I received three FlightAware antenna’s and FlighAware Pro Plus sticks from an UK supplier. The delivery was decent, and I created a test rig in the attic. Results in compare to the Chinese antenna’s were immense. Reception was marvelous, even indoors at a maximum of 10m altitude from the ground.
The outdoor setup was a virtual clone, with a longer antenna cable, 5m instead of 1m. The target, a roof of an apartment building hosting several P2P-links, FM and DAB equipment, both for reception as broadcasting.
- RaspberryPi3, ArchLinux, Dev version of Dump1090
- FlightAware Pro Plus + USB extension cable
- dAISy HAT
- Extra Chinese stick for POSTAG reception
- 5V@3A power supply
- 5m sma/n cable
- Flightaware Antenna using self-amalgamating tape for the connector + N plug.
Edit: everything in a box to prevent dust indoor. No shielding
Going, with two cables.
The results were dramatic. Virtually no reception at all. Since this is one of the tallest buildings, having a complete free horizon, and an usbstick which was supposed to do filtering, this is a bit disappointing to put it mildly.
I have replicated the setup including longer cables in the attic again, there is no worst reception using the 5m cable or improvements of using the 1m cable. At this moment (1:55am) a few targets around 300km remain in sight.
Obviously I could go back on the roof hook up a short antenna cable directly to my laptop to see if that improves reception. I could also take a replacement antenna and/or usb-stick. But since I also have access to the PiAware setup changes in software are also viable. I have already tried to change the gain, which did not really change. Any guidance is appreciated.
