RTL-SDR for airplane tracking

Post by Amit1Sorz » Thu Feb 20, 2020 8:11 am

Hi everyone, I'm a total beginner with sdr devices..
I bought one from amazon: https://www.amazon.com/gp/aw/d/B011HVUE ... prod_image

I want to use it for airplane tracking, Is that a good one?

I never used that type, but go forth and be creative!

By airplane tracking I guess you mean ADS-B? Yes that will work well. Use the smaller elements collapsed, and get the antenna outside and up high.

I am new to this too. I have installed SDR# on a windows 10 machine and built a small antenna called a "quarter wave monopole ground plane" build to this design:https://ketil.com/la2dna/antenner/PMR44 ... ntenna.htm.

I don't get any reception and I don't know if:
  • the antenna is not up high enough (it is located in an upstairs bedroom)
  • even though I live on the flight path to East Midlands Airport, all the planes have stopped flying due to cover-19,
  • or some other reason.
I have also tried to install dump1090 which I believe is needed, but to no success.

Any help would be appreciated.

You do realize that this antenna is for an entirely different frequency, do you? You'll need one for 1090MHz, so the dimensions for this type of design should be in the vicinity of 68mm (not 158mm as in the link above).

I have made a bunch of spiders from stripped telephone wire and SMA PCB connectors, I usually use 8 or 16 radials depending on the wire diameter. They work OK if you cut the wire precisely, but for best performance you'd need to first leave the wire slightly too long (i.e. tuned to too low frequency) and then work your way up by clipping the ends off while doing measurements with an antenna tuner. The downward slope on the radials should be somewhere around 30° instead of the 45° typically shown, that gives you a better match to the 50 Ohm SMA cable you'll be using for the RTL-SDR. Again, if you can measure the antenna that will be much easier.
