After lots of Antenna threads some might be interested in a range comparison.
I was using the Jetvision A3 Antenna for several months. This was required for the AirSquitter and the built in GPS functionality
Now i changed it to a new Vinnant antenna. Some know it already, it’s the guy in Slovakia buiding individual antennas.
From the values the antennas do have the following specifications
Jetvision: 5dBi gain, 60 cm
Vinnant: 7.5dBi gain, 100 cm
As the new tar1090 interface provided by @wiedehopf offers an easy way to highlight the current range, a comparison has been made easier.
To the left the Jetvision, to the right the Vinnant. You can see a slight improvement from range, but it would require more testing for verification. The blue line shows my max range per terrain, set to 40.000 feet.
The small gap to max range on the north east is caused by my own roof which i cannot chnage.
