    2x 'D Sackel' style clamps around the metal base direct to pole, or an L bracket with a hole in the bottom for the antenna to poke into which is then bolted to the pole. The bottom nut should unscrew without affecting the cable and give you ability to put a plate between and re-attach

    G'Day Oblivian.
    I think the L bracket is going to be the only option - the antenna does not have a metal 'base' / mount to use D clamps.
    It has a large nut, then a spring, then the fibreglass tube. It looks like it should be mounted on a roo/bull bar on a car or truck!

    After unscrewing the nut, it won't slide off over the N connector on the end.
    And, even if it did, and I had a hole in the bracket big enough for the N to go through, the hole would then be too big for the 1/2 inch threaded section I need to screw the nut onto.

    The only thing I can think of is to hacksaw a 1/2" slot into the L bracket, slide the antenne in, then screw it tight with the nut - which seems like a weird way to do things to me.
    There's no installation instructions, and no reply to tech support at Mobile One (as yet).

    Regards, Greg.

    Hello all!

    I am using:

    - Hardware:

    Receiver:
    RTLSDR RTL2832U with R820T Tuner: http://x264.nl/dump/rtlsdr_antenna.jpg
    For 1090MHz of course not using RG58 coax, but in my case some white tv/dvb-t/satellite coax. (Still could do better.)

    Antenna:
    Homemade groundplane antenna: http://x264.nl/dump/ads-b-antenna-gr...ane-proper.jpg
    Calculator: http://www.csgnetwork.com/antennagpcalc.html
    Design: http://ketil.com/la2dna/antenner/PMR...ne_antenna.htm
    (Setup cannot be used 24/7 due to mast not being permanent and only up when the wind is calm. And there is so much else to do with the RTLSDR.)

    - Software:

    ADS-B decoder:

    http://sdrsharp.com/index.php/a-simp...-using-rtl-sdr
    A new gui version has been released: http://sdrsharp.com/downloads/adsbsharp.zip
    This decoder is still in heavy development, but first tests make it better than rtl1090.

    - Virtual Radar Server and Flightradar24 Feed
    http://www.virtualradarserver.co.uk/ version 1.1.2 ( http://www.virtualradarserver.co.uk/...RadarSetup.exe )
    http://feed.flightradar24.com/ beta 26 (2.26) ( http://feed.flightradar24.com/updates/226/fr24feed.exe note I changed 225 to 226 which is not on the page )

    a) run adbs.exe (runs on tcp port 47806)
    b) run virtual radar server, connect data source to tcp port 47806
    c) run inside virtual radar server via options: rebroadcast server, format BaseStation, port 30003
    d) run fl24feed.exe and connect to tcp port 30003

    Result: http://x264.nl/dump/adsb-flightradar24.jpg

    G'Day Jarod.
    Finally a step-by-step guide on how to do it on the cheap ! I'm impressed.
    Well done. I'll be giving this a try ASAP.

    Thanks, Greg.

    Hi people.
    I dont know if this was already posted.... It is about RTL1090, some people developed a software to do this...
    I am at this time doing some testing with RTL 2832U (not yet R820) and RTL1090 plus Virtual Radar and it is working.
    Waiting for arrival two R820...
    Software link : http://www.hamradioscience.com/rtl10...on-de-website/
    Not sure if this is/will be supported by FR24, and wil be gratefull is some advice about this.
    Cheers - Juan

    ADSBSharp is much better. I get way more planes using adsb#.
    And yes it would be nice if FL24 would directly support AVR Receiver input.

    Here is a video of me playing around: http://www.youtube.com/watch?v=HAzzbxnroeA&hd=1 - 2x RTLSDR: ADSB# + Virtual Radar Server + SDR#
    Not the best video ever made, but i tried to match called planes on the radio, to the map.

    Hi Jarod,

    Good ... I wil try with ADSBSharp as soon as possible.... but it seems that not shows the messages passing ... it could be better this way.

    There's a free, independent Review of the microADSB over on the Radarspotting forum and a free to enter competition to win one together with a PlanePlotter licence:

    Hi GregHudson

    I started on ADS-B in 2007 with SBS-1, then followed with RadarBox.... did several antennas ... including two 21 stacked dipoles coax colinear....
    Since one week started to play around with ISDB-T dongles and become astonished with the results.
    Also noticed that for me it did not worked using a 10 dipole collinear coaxial..... but I a getting eazy 180 NM with the dongle original antenna
    modifyed to clone the whip of the radarbox supplied aatenna and let it on the window... (ok , I live on 15 floor ..)
    Still doing tests ... with one E400 and one R820T... several antennas, several softwares ....
    I found these dongles cheap and marvelous for playing around.


    Cheers - Juan -
