    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.

    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:

    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

    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.

    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:

    https://flightaware.com/adsb/stats/user/matysldn
    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.
    Slim Jim antenna 3/4 wl
    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.
