I have two coaxial antennas side by side 600 cm apart. HiAnt is of 8-116 mm elements and LoAnt is 5 -113 mm elements some 2.5 m lower. Both feed RPis which feed to FA and FR24 i.e. two radars at FA and 2 at FR24.
Here is the data collected over 10 days from FA and FR24 stats pages as well as VRS software. Can anyone explain the last two results? Percentage shown is HiAnt relative to LoAnt.
+11.4% more messages received by VRS
+6.8% more positions reported per FR24 stats
+5.6% more hits reported per FR24 stats
-1.8% fewer positions reported per FA stats
-27.0% fewer messages received per VRS for an airway ranging from 80 to 120 nm distant.
