  • Hi!
    I'm looking to expand my ADS-B setup with a receiver for voice comms as well. I'm looking for a good outdoor VHF (airband) antenna, preferably one with about 10m of cable terminating in an SMA connection, though i'll take other options into consideration too of course.

    Anybody with a recommendation?
    Thanks!

    • Well i have tested a few of things and the best was, flighware prostick with cantenna.

      i try the line amplifier but only lost all planes i think i need the in line power to make it work.

      i purchased an antennas that are fixed to 1090, but worked as same as cantenna.

      used to have yellow stick with filter but, blue worked better, also tested blue with filter ( i know it has already a filter, and seems to get 1-2 planes more but dont worth the invest, so just blue alone.

      so, what do you recommend ? i think i just need to test the in-line amp to see if range improvees

      • AlejandroM:
        I dont think you will get any (or much) benefit by using the Satellite in line amp with Flightaware ProSticks as both orange & blue ones have built in amplifier, which is sufficient.

        However if you want to try, you will need DC Power inserter for Satellite in-line amplifier, to be connected between DVB-T (Prostick) and Satellite Amplifier. You will also need an AC to DC adapter (AC to DC 12V ~ 18V) to feed DC to the amplifier through power inserter.

        If you want a good antenna, go for Flightaware 26" antenna (price $40).

        With this antenna, use of the external filter (which you already have) may be necessary even with blue ProStick

            What do you mean by it, power inserter OR Flightaware Antenna?

            Comment


            • power inserter for now, i open the two links you sent me i select ASKA (https://www.ebay.com/itm/221457117112) is the same brand as the line amplifier. i am just lookin for the AC to DC adapter to make it work.

              i also purchased this one but has not arrived yet.

              https://www.ebay.com/itm/302756240474

              also i saw this ones in amazon, i think are the same as line amplifier

              • Make sure you're getting the right connector for this antenna at your cable. Otherwise you need adapters which always impact gain.

                I am using a similar one:
                https://www.ebay.de/itm/ADS-B-Antenn...z/193043127488

                Aren't you using the blue Flightaware stick? Then i have doubts if an additional amp will improve something

                • yes i am using the blue stick, sorry for delay answering.

                  i just notice my cantenna works as good as the green antenna i show you, BUT... the cheap green antenna show more (with positions) 3-4 in relative to cantenna..

                  so i left one and one, in the same city.

                  they get diff planes, at the time of the screen shot it seems to be the same,

                  • You should use/show the graphs. The number of messages is here the interesting part for both

                    • i installed all by myself, then i saw the post, so i dont know yet how to install only graphs.

                      i will take a look again to this post

                      • Those graphs Alejandro: https://forum.flightradar24.com/thre...1090-et-cetera

                        I always recommend that people switch over to the more current dump1090-fa as well, using the bundle listed in the thread linked above.

                        • Im not too sure if that was posted here but Im finding very useful antenna calculators on that web site. Looks like the owner of this website was(is) involved in 1090Mhz aswell

                            Nice looking drawings & designs.

                            Have you built any of these? How was the performance?

                              At the moment I built my hardware and software based on your posts. This is how it looks like:
                              Picture no: 1 - Antenna, dipole 68mm arm, sorry for lack of focus.
                              Picture no: 2 - RasPi case build by using cotton buds box
                              Picture no: 3 - This is where I actually live. No open sky at all, high buildings around me, only one advantage is that my apartment is 35 meters above the ground and 200 above the sea level plus lots of busy airports around.

                              With this configuration and location this is what I get:

                              Picture from my dump1090

                              And this is what I just build following instructions from the website. I haven't had time to test it yet.

                              I will post here once i manage to install the antenna and test it.

                                Nice built.

                                Experimenting with different types of DIY antennas is fun.

                                I also live in a high rise building, surrounded by other high rise buildings, and I am not allowed to install anything on roof or projecting outside the window, but that did not stop me from experimenting with DIY antennas.

                                Have fun.
