    1/4 wave is ~5.8cm, a little less in the cable, but in that third picture above the length appears to be much less, what is going on there? i mean the lengths after the first Ts but before the final T, that transforms 25Ω -> 100Ω, is it just the perspective?

    4.1cm taking into account the velocity factor of Teflon. Take two sma connectors and file them down so they both fit into a single crimping ferule. Make two, and screw into Tees like in the picture, you're done. The four antennas connected to that network don't need particular length as long as they are the same. Final cable going to the rx can be any length. Space the antennas 3/4 to 1 wave apart, center to center. I'm thinking of building a batch of these and sell them on my website, already got a name: "TrueRC's Quad-Link" Probably 20-25$ a piece, quite cheap considering the price of the Tees and connectors.

    The gatling earned its name! That thing punch trough everything!
    In that video I place over a mile of forest between plane and GS. So much that my UHF is lacking behind, I had to switch to 1W power.

    The Gatling 2.4 is a success! 15.5db, it beat my 12T helical in gain, beam width and axial ratio!




    It measure only 8"x8", here's a picture with a comparison:
    The smaller one is a regular crosshair 2.4.

    Hugo, amazing stuff.

    Question: may have already been asked but when will we see a 5.8Ghz version?
