I had high hopes of getting better reception by purchasing the FlightAware 1090 MHz ADS-B Antenna - 66 cm / 26 in. I had read about “Your cable matters” over and over again on here so I decided to purchase a Proxicast 10 ft Low-Loss Coax Extension Cable (50 Ohm) - SMA Male to N Male at the same time. Install them together.
Previously, I had made a simple, cheap and dirty Spider antenna and had adapted a coaxial cable to it and used an adapter to get the coaxial cable to fit to the Flightaware Dongle.
Results are what I would consider to be roughly 3 - 5% lower with the new antenna.
Not the end of the world but at the same time not an improvement at all.
Setup: Externally mounted Antenna and Raspberry Pi with as noted above a 10’ cable to connect the Flightaware antenna to the Blue Fightaware Dongle.
Installed height is roughly 20’ AGL and probably 23’ ASL.
No obstructions to the view of the antenna, nor was there any changes to the installation location vs the homemade Spider.
