    Ok. Thanks to all. I will see what to do after all recommendations.
    Covering the Canary Islands, Madeira & North West Africa
    F-GCRR1: 565 meters high. F-GCRR2: 614 meters high. F-GCRR3: 604 meters high.
    F-GCRR5: next to the airport. Improving Canary Islands and Western Sahara MLAT.

    Hello, I'm from Aceh - Indonesia, I put the receiver in outdoor enclosure too, but I added fan with solar panel on it, but the temperature still reach 62 celcius when sun light really bright at mid day. Outdoor temperature is about 34 Celcius, I think this receiver need some heat sink for its processor.

    Pak Munawar,

    May I suggest that you build a small roof over the box. Prevent direct sunlight from striking the box. It will reduce the temperature by a few degrees.

    Cik Limpost,

    Thanks for your suggest, I must think what kind of roof suitable for the box that really strong and realible, because I will put the box on top of telecom tower.
    When first time I receive I put the Receiver on that tower, but I got electric problem to the box, and with new box I installed PoE support with 12v Adaptor than I use DC-DC converter to 5v. I think it more safe with 12V power supply to my Box than 220V AC.

    Yes I would recommend you look at a PoE (Power over Ethernet) solution. The most likely device to fail in an extreme temperature is the power supply. That power supply adapter is not rated for such a high temperature operation and will most likely fail very quickly.

    When I was a civilian contractor for the military, one of the tests we had to do for all new electronics was to 'heat soak' everything for 5 days at 50*C. In theory this aged the electronics. For ever 5 days in the 50*C heat soaking room the electronics was aged 6 months. It was a test to spot any weaknesses ... their rule was if something is likely to fail it will in the first 6 months of its life. So keep this in mind, a high temperature will age the electronics faster.

    The main issue for receiver is... We want to put antenna as high as possible but with coaxial cable as short as possible too.

    Thats why we need to put receiver in outdoor enclosure than we got another problem with heat, if Mr 1090 Mhz said that Power Supply Adapter not support with extra heat how about with DC-DC Converter ? I bought it from aliexpress.com (picture attached) and I hope its can stand more longer in heat condition.

    My friend, ATC from WITT (F-WITT3) put the receiver in ATC Tower Room but the receiver got only 20nm than its come better after fr24 change/upgrade with other receiver maybe with noise filter, because too many RF signal from VHF Airband, HF, etc from that tower. I tried with flightaware reveiver too on that ATC tower than it only got about 50nm.
    F-WITT3 receiver installed in ATC Room with Air Condition, but it still about 45-50 Celcius (picture attached). I think receiver generated more heat by its self than environment condition.

    Maybe in this forum we can share best, small, cheap cooling system and RF protection for the receiver

    My FR24 receiver is also running at between 56-60 C in doors. The design must make it run so hot I think.

    Anyway, have you come up with an idea how to keep your waterproof box cool up the telekom tower?

    How about this enclosure? As long as you position the open front to the North or South, the sun wont shine directly into it.

    hello to you Sir and you started a very good discussion!

    so there are couple of issues for you:
    1) temperature of the FR24 receiver
    2) ?PoE
    3) RF intereference

    for issue 1, I believe FR24 have no cut off temperature to say below this temperature receiver ok above this temperature receiver not ok.
    For my receiver the temperature runs around 55-57degree C in my room, no air conditioning or fan is running most of the time. What is yours limpost? And for you peter 1090mhz your receivers runs a bit warm even winter time? One thing for sure is the receiver does get quite warm. So if you put it outside in an enclosed box it is not surprised to see it go around 65 degree C or more. Our friend lazarote might be able to give a bit of insight as to how hot he receivers get and whether it works fine.

    Very neat work for the receiver in the enclosure! I am really impressed by it.

    2) For PoE FR24 somehow is not keen with it - Mike has said Gunter, the maker of radarcape/FR24 receiver has reported problems with powering the receiver via PoE. They tend to get short circuited. The advice by who (a member in this forum) is so long the PoE at certificed at IEEE 802.3af for both power injector and splitter it should work fine. So just make sure you can source certified PoE injector and splitter, brands like D-Link do. see the post by mike here http://forum.flightradar24.com/threa...ll=1#post61668
    it really is a shame for someone who can place the antenna high but due to cable length/receiver power supply issue that height is limited.

    3) Yes, being at a place where many frequency is running will degrade ads-b 1090mhz reception. So using a band pass filter/3 pole filter is preferred in situations like that.

    Now, this leads to...

    a) There is an active PCB antenna available from this website http://shop.jetvision.de/epages/6480...Products/68200. The bias T is powered by USB power (5V i think) and injects power to the antenna's build in amplifier. It has a 21db gain after amplified so it should be able to help in your situation since yours is a tall tower, and you might be able to place the receiver and it's enclosure further down/at the base with a long cable but less signal loss? It also comes pre build to receive 1090mhz only so RF interference is avoided. A bit more information here: http://forum.flightradar24.com/threa...6871#post46871
    It is expensive and also perhaps there might be additional import charges/tax though so that might be a problem. Just a suggestion of course, so that you know this product exists.

    b) We don't often hear from ATC people on FR24 and I am thrilled that at WITT one of the receiver is managed by ATC people. WITT2 & 3 both have good ranges (WITT3 goes furthest!) and it was quite a wait to finally have a few good feeders from there feeding to FR24. Thank you!

    I presume you should have a few contacts of ATC around, there is a 'wish list' coverage for indonesia, please see here: http://forum.flightradar24.com/threa...ll=1#post63616
    Perhaps you can help find potential hosts for the list of Sumatra? Kepulauan Anambas is also high on the wish list. Don't worry... if cannot never mind. There is also a FB group for Indonesian Feeders found at the radar indonesia thread top of page 7. Keep showing us pics of the set up very nice to see your work!

    (by the way, the picture with workers at the top of tower, they don't seem to be wearing any harness at all?)

    Very usefull information share from North Borneo, I'm really agree with all your opinion, we can use noise filter, good POE splitter or maybe we can make outdoor enclosure with good cooling system, but of course it will need more money make it.

    I'm just want to upgrade the receiver with low cost and DIY base on my electronic knowledge or from forum like this one.

    FYI...
    T- WITT1 my first data share with RTL USB dongle but not 24hr and I'm using not compatible antenna (L-Com 5.4Ghz wifi antenna)
    IMG_20150309_080020.jpg

    F-WITT2, Installed on telecom tower but now I move it temporary due to electric problem.
    My first box directly use 220v with Power Supply Adapter in it.
    IMG_20150309_075845.jpg

    F-WITT3, this receiver applied by my friend, he work as ATC, the reveicer install in control room and antenna on the roof.

    Temperature compare F-WITT2 (in outdoor box) and F-WITT3 (in ATC room), 8:15PM GMT +7

    for your own setup T-WITT1, perhaps you can DIY an antenna, either a dipole or CoCo... so you can get better signal reception. Antenna thread has info but too much so hard to find.

    Hm for WITT2 perhaps is best to approach via PoE and wrap with aluminium foil to reflect heat? You can send FR24 support an email asking their thoughts for the receiver being at the top of the tower and you are concerned about temperature. They will have some information since they have thousands of receivers and I am sure there is a similar case to refer to.
