    @jepolch - What improvement did you see in a cantenna vs spider? (Forgive me for not backtracking the 79pg thread to find the post) I'm tempted to build one over the weekend to see how it compares to my cantenna!

    ADS-B DIY Antenna

    One landed on my desk yesterday, not sure what I'm going to do with it yet :D Installed all the rtl & dump1090 stuff, had a crack at rtl_airband but its spitting out errors when trying to run 'make'. More investigation and learning needed. I've also got an R820T2 on its way, will see how that...

    I've mounted my cantenna inside a piece of 90mm stormwater pipe with 2 endcaps. Seems to work ok :) Coax feeds through the bottom, silicone around the hole.

    Came across this while researching high pass filters. Might interest some of you :) http://discussions.flightaware.com/ads-b-flight-tracking-f21/real-world-antennas-and-filters-t19849.html Meanwhile down under, I'm working on a pulley/winch system to tilt over my 7m tower so I can put the...

    ADS-B DIY Antenna

    I wonder what the performance of this antenna recommended by flightaware would be like compared to our homebrew ones: http://www.dpdproductions.com/page_vhf_air.html#adsbout Its a little on the expensive side for me, $150! I've modified my splitter with 2.2mh inductor and a 100pf ceramic...

    Fantastic! If you can keep it simple and it works, then why not :) Good to see another like-minded indivual playing with a PoE rPi!

    Thanks mate. It works well so I'm happy with it :) As for the temp sensor, I run a package called rpi-monitor (http://rpi-experiences.blogspot.fr/p/rpi-monitor.html). On their website somewhere, they had some instructions on how to add in a DS18B20 or DHT22 temp sensor. It was a little hard to...

    Nice setup mate. What are you using to drop to 5v for rpi? How long is your PoE run? I'm using a 24v PSU (had one spare) with a DC buck converter to drop to 14v for the amp, then up in the box I've got another DC buck converter to drop to 5v for the rpi. Haven't tried direct connect as the...

    1)Part of my logic was to allow the dongle to dissipate heat a little better and also just to slim it down a bit. Initially I had a fan mounted on the lid of the box but I thought it may have been introducing a bit of EMI so I unplugged it. Everything still running OK, highest internal temp I've...

    Classic case of user error then! I figured something like this might happen when I used this splitter, gave it a shot anyway though. This splitter is a "two halves joined" design, so there is no back cover to pop off. The seam goes lengthways through the F connectors too. Perhaps this is an...

    Hi mate, thanks for your reply :) I've removed the amp & injector, seems to be an improvement! Stupid thing. Strange that it works OK at slightly lower elevation when side-by-side with the magmount on the gutter, yet further up the roof it gets worse. Whats your signal like if you disconnect...

    ADS-B DIY Antenna

    I'm back, and I'm stumped! A couple of months back I finally got around to raising the antenna onto my tower. Strange things happened.... The higher I had the antenna, the worse the performance was. My 2nd SDR & magmount whip antenna was still setup on the gutter and getting much better...

    Nice work, Kyle! Looking forward to seeing some pictures

    Thanks for the plot :) I'm quite interested to see how it will perform once above the roof line. I still find it quite impressive how well it works in its current setup. I've considered putting the antenna on the tower & running a 15-20m RG6 feedline back to the receiver. I calculated the loss...
