    Good idea, everybody interested can retrieve the full information by sending me an e-mail and then we can see how uniform (or different) results builders may get compared to antennas they have tasted at the same locations!

    Hello, first time posting. i have been member for many years feeding with my raspberry. now i have 3 locations and i am looking the best antenna for me.

    today i was testing the cantenna, i did it with no measuring tool, and using the yellow dongle from flighaware and just get 1 plane =(

    then i remember i had the filter also from flightaware and installed it, and in less than 1 second i receive 30 planes, at 200nm+ i feel very happy, and i will install a filter in each of my locations.

    i will continue testing what will be the best for me. 200 nautic miles are very good!

    Best filtering at a reasonable price in my opinion is provided by the rtl-sdr LNA.

    It requires a bias-t though or the receiver needs a bias-t like this:

    But if you already have the FA stick, then getting a FA filter is probably cheaper than changing the whole setup.

    also the coaxial cable is like 10 meters lengh i am thinking at least to cut it to 5-6m that will help?

    I've read about comments to have a better performance if you use a long USB cable and a short with the stick close to the antenna...

    I struggled to get any good results from a cantenna and eventually went with an 8 element co-axial cable co linear. More complicated to make but not really that difficult. I eventually added a flightaware filter and a satellite preamplifier.

    This is what I get typically now and I doubt if I can improve it further because at my location I have hills to the west.
    Anyway I keep upsetting my wife who feels that at 75 I shouldn't be climbing ladders to the roof!!!
