The 16Right ADS-B stations use one seven element, and two nine element coaxial co-linear omni-directional antennas. Two of the antennas were built by Dave at DPD Productions in California USA, and the other custom built by Grahame Hutchison.
One DPD antenna is connected to a Raspberry Pi using LMR-400 coaxial cable, with a run of approximately 10m. Over this length the attentuation within the cable is 1.3dB with 74.2% efficiency. N-connectors are used for the two joints, one connecting to the antenna fly lead and the other connecting to a short adapter lead into the decoding unit. The other two antennas are connected in a similar fashion to a Kinetic SBS-3 Receiver, and a second Raspberry Pi respectively.
Currently, data is uploaded to 16Right ADSB from three locations in the Sydney region, providing coverage of more than 235nm from Sydney International Airport in all directions. Each station provides unique coverage, outlined below, as well as providing redundancy for each other.
In order to provide the data for this website, a custom written Node.js script reads data streamed from either dump1090 (for the Raspberry Pi receivers), or Kinetic Basestation (for the SBS-3 receiver). After performing numerous processes on all received data, it is then uploaded to the 16Right ADSB server. This enables the features such as the Live Flights, Live Map, and Sydney Airport (YSSY) Status.
In order to reduce the shear volume of data received to a level appropriate for display online, flights and positional data are logged only when information changes at 5 second intervals.

From the first data upload and basic website, this project has evolved and advanced, becoming increasingly complex and useful to an increasingly large base of users. In the future I hope to further develop 16Right ADS-B to become even more informative to a broader range of end users, with a variety of new challenges forming as the motivation for the continued development of this site.
Thank you to CASA (Australia) for answering numerous questions regarding the continued development of this site, and providing material relating to ADS-B operations in Australia.
