DIY ADSB Coaxial Collinear Antenna Project

[Grahame Hutchison]

There is some Tropospheric Ducting going on in the southern ocean at the moment, southeast of Bass Strait, and both my
Northern Beaches and Eastern Suburbs ADS-B Stations are having some great range results. The theoretical maximum range
for ADS-B reception is around 230nm.

Station A - Northern Beaches 395.1nm (731.7km) - DPD Coaxial Collinear Antenna
Station C - Eastern Suburbs 373.4 (691.5km) - My DIY Coaxial Collinear Antenna

The Flights involved here were JQ212 AKL-MEL, JQ164 MEL-WEL, QF152 AKL-MEL, JST171 MEL-CHC, and I think I saw an
ADL-AKL flight as well.
