    Just recently changed from an FA Prostick Plus to an RTL-SDR v3 & LNA. Seeing significant improvement. Still need to get it mounted on the roof but not fancying the ladder climb :P

    I'd really wonder if this is working, I don't think so
    In the same position I had another RPi running for almost 2 years without any issue and still working but not for the same purpose.
    I think, a fan and trying to avoid direct sun light is enough to keep this implementation up and running for many years.

    Many years ago, we had a whole PC running on the rooftop inside a junction box for antenna and routing purposes with no issues. Great years!

    The only danger could be a nearby thunderstorm.

    I've no idea, I was just wondering and yes it's worth a try at least :-)
    Temperatures here are between -20 and +40 C, in the sun even more. It definitely will be a stresstest for the equipment :-)

    A secondary sun shield to keep the entire box from overheating probably helps.

    But with a fan why shouldn't it work? In the winter the heat of the pi keeps the complete box at least a little bit dry or drives out moisture that might get in.

    What do you think would fail?

    By using FlightAware N-Type Antenna 5.5dBi all initial tests in the temporary location was very good.
    Next weekend device will be moved to the permanent location near LXS/ LGLM airport in Greece.

    Details about all parts used for this project and the radar name will follow.
    As promised, my new radar is in operation, with name T-LGLM1.

    Below is a list with the parts used for this implementation:
    1. Raspberry Pi 3 - Model B+
    2. Raspberry Pi Power over Ethernet (PoE) HAT
    3. Tp-Link PoE Injector TL-PoE150S
    4. Kingston Micro Industrial SDHC 16GB Class 10 SDCIT/16GB
    5. FlightAware 1090MHz ADS-B N-Type Antenna 26" - 5.5dBi
    6. FlightAware Pro Stick Plus (USB SDR ADS-B Receiver)
    7. Hyperflex 5 Coaxial cable (4.5 meters)
    8. N connector (CO.N.54M-S)
    9. SMA connector (C.SMA.HYF5M-CR)
    10. Waterproof Ethernet Cable Gland - RJ45 Male to RJ45 Female
    11. IP66 Junction Box171X121X80 mm

    My ADS-B setup project

    Hi Guys!
    Here is my setup

    Hardware used:
    Raspberry Pi 3 B+ (3A power supply)
    Dump1090 provided by Flightradar24 (i use my own API to show the map without the limitations)
    Generic RTL-SDR Dongle (R820T2 Chip) + stock mini antenna modified to match the 1090mhz range.
    USB extension cord
    Ferrite bead
    Gewiss Junction box 240x140x90 (Model GW44208)
    Power Cable, white color.
    Black clips with adhesive tape to maintain the cables firm.

    My Flightradar24 radar name is T-LIRN24
    Airport: Naples, Italy

    Currently my maximum range is of 100nm

    Thinking of buying a new antenna to put on the roof.

    Also, i have a PDF with all the details but can't post it here.
    Here is another picture with the setup running.
    Obviously everything is closed and water tight.

    What's yours?

    Cheers!

    Dear Kenny,

    I have described my equipment here https://forum.flightradar24.com/thre...ll=1#post92475. As you can see all the electric components are stored in the case of a derelict PSU. The fan works with 5V from the power source to prevent overheating (dump1090 causes about 20-40% CPU load to the Raspberry Pi). I stored it outside, but in a dry and roofed place. Due to the permanent ventilation, some dust accumulates inside the case over the time (I have disassembled it recently). I suggest using a grounded metal case to prevent QRM.

    Kind regards from Karlsruhe, Germany!

    Great ideas and pictures everyone! I am wanting to build my own outdoor box but I just am not sure if it needs to be 100% waterproof and enclosed or if it needs vents and or a fan? I live in the US in Oklahoma and the box would be facing the west side of the apartment getting the PM sun where our temps outside reach ~100F/~38C with relatively low humidity. We are currently heading towards fall/winter so our hot days are mostly gone already.

    Maybe my question was not clear.
    Is the result better if you use the original company receiver or is it the same if you use a RPi?
    I believe the result should be exactly the same because I believe it’s only the antenna that masters.
    Am I right?
    That would depend on the quality of the receiver, its sensitivity, filtering etc etc. Remember that the RPi in the ADSB sense is only as good as the receiver device you attach to it, after all it is just a computer.

    You can, but some like to compare hardware side by side in a test environment (and there was/is? providers that contractually restrict who you send data to from their hardware)

    FR24 receiver

    Antenna(s)
    FR24 supplied 1090 MHz

    Software
    Virtual Radar Server
    ADSB Scope
    ModeSMixer

    Range
    FR24 Receiver range from VRS with Range Rings at 25nm increments up to 225nm.


    The gap to the west is caused by my neighbors two story house with a large roof (almost a whole floor in height )
    The gap to the north-west is from a park with tall palm trees across the street.
    As there is no east-west traffic in range of the feeder there is a nice gap towards the south.

    FR24 Receiver range from VRS with Altitude Range at 25nm increments up to 225nm.


    Setup



    The galvanized steel pipe is 0.47m (1ft 6") above ground level.
    The FR24 antenna base is at at 10.6m (34ft 9") above ground level while the other antennas are at 5m (16ft 4") above ground level.

    The FR24 coax cable is just long enough to reach the top of my window where the feeder is located so that's why I could not put the antenna any higher.

    I plan on moving the PlaneFinder and FligtAware antennas to the top and change the construction resulting in a height of 13.5m (44ft 3") above ground level for the antennas. But it's going to take a lot of planning and work.
    Hello, I am not an expert and would like to ask a basic question:
    Is there a reason to have 1 antenna for each system or would one antenna connected on RPi feeding the 3 websites give the same results ?
    Thank you for your guidance and best regards
