ADS-B Cantenna

For the ADS-B demo that I did for DC909/OWASP IE  I used a cantenna which is like the one detailed here (and other places)

It's basically a soda can and a bit of wire both cut to 69mm (1/4 wave), with a coax cable feed. You will need a F-connector female-to-female connector and a F-connector to SMA adapter (or adapter to whatever antenna connector feeds your RTL-SDR)

It's very simple to make (other than, assuredly, cutting yourself on the can). Before I "tuned" it I was getting 30-60 mile range. Excellent for the greater LA/IE area.
