    PHILIPPINE RADAR FORUM

    I still not checked yet. However, I suppose not so strong interference source are near or here.

    Most important requirement is resonated element and good ground plane. Then small antenna.
    At first I'll try to cut the element as 1/4 wave as you said, then put radials for optimum resonance for 1090MHz.

    Trying collinear will be on next stage

    Thanks and regards,

    Awkie John, i had no luck with collinear, i made three with different materials but seems to me not good for receiving. I ended up making my own design that everybody also followed and tested, and it works. They have there Spider i have my own complicated spider. And by the way, i added a filter and an Amp near the antenna powered by an injector. im using a modified dump1090 for my raw viewing. What is the brand of your dongle? Guys, dont be confused, my location is not from PH but i am familiar with the place, been there for 40 yrs of my life thats why i enjoy staying and monitoring this thread. My FR24 radar is T-KSAT5, am 5 minutes close to San Antonio International Airport Texas. I will add a radar next year near Laguindingan Airport about 30minutes. Here is my design.

    Already purchased materials today. 10 meters of 3/4" GI pipe.
    1" seems too heavy to raise up by my self.

    I'll try raise up it and install it as soon as possible by tomorrow morning.

    Solutions for Mounting Your Receiver Up Your Mast

    That's good idea to use plastic bottle!

    But before that, I need to cut antenna element to resonate 1090MHz.
    Attached element for dangle is too long to use at 1090MHz.

    I also used 20 meter USB cable in Japan, but it was not extension. It was "Active repeater USB cable".
    On USB industrial standard, 5 meter of extension is limitation of USB electric characteristics.

    Anyway, thank you so much for your kind informations.
    I'll try my best effort for extend range of receptance!

    John-h there is another solution I use here for receivers that have ethernet connections and are mounted on the mast making them inaccessible without climbing. They use the power connection up the mast to the receiver to transmit the data directly to your modem's ethernet port. Using these, the distance from your receiver to the modem can be 100 meters or more. Restarting your receiver is as simple as turning the power to the receiver off and back on. If your receiver is on a high rise plugging to any outlet up there will provide the data to any receptacle down below provided they are on the same transformer.

    Some CDRKING locations have them and if you are interested call around till you find stock or order them online. Here is the device.

    Ten meter usb extension cables are available in Manila. Below is one such ad, give them a call if you are interested.

    What kind of information do you want?
    I'm just connect RasPi2, dongle, and antenna, then type command described in "Instructions" provided with FR24 site below.

    The world’s most popular flight tracker. Track planes in real-time on our flight tracker map and get up-to-date flight status & airport information.


    No more settings are necessary except of above
    ohh ok no information, John gave it but Thank you

    Yes John,
    I'm using RasPi, DVB-T dongle and magnet antenna which come with dongle now. I brought these from Japan since I could not buy items in around Metro Manila..

    as you said, I could received signals on the ground of NAIA even poor equipment, however i'm not satisfying.
    therefore now planning to bring another small sized co-linear from Japan but it will be June. I need small antenna since i have receiver in my office

    Anyway, thanks again and my best regards to all of you.

    John-h back several years ago when I was tracking for FR24 with dongles I used usb extension cables to increase the distance between the computer and the dongle/simple antenna. This allowed tracking at my location almost as good as with a co-linear antenna of about 150 miles. Just imagine what you could accomplish if you could get your dongle and antenna outside.

    I mounted the dongle in a 1 or 1 1/2 liter upside down plastic bottle with the bottom removed with the antenna taped to a bit of bamboo that supported the whole thing. Dongles in my case didn't work using longer than 10 meters of usb extension cables.

    I've just started feeding with new receiver at near from north west side of NAIA.
    I can't promise to feed the data eternally, however I want to be family of you guys in here.

    John-h glad you got setup, I have a filter setup on my main FR24 map to show your trackings. So far looks like you fill in on the ground aircraft in front of NAIA Terminal 3. You're probably noticing more planes you are tracking on your app but that is because FR24 just uses T- designated receiver's data to fill in when no other F- receiver is tracking the same aircraft.

    You are filling the shoes of F-RPLL1 which was on a hi-rise looking down on the same area before it went missing.

    What kind of receiver are you using? A dongle with a magnet mount antenna maybe?

    We are looking forward to your long term participation.
