    ,,, maybe yes, but you need other distances between the biquad antenna..!!!

    How to determine the distance between the biquad antenna and the aluminum sheet? Or maybe you can help master?

    Sorry master, if this antenna is made with a thin sheet of aluminum, will it have the same gain or will it get worse?

    It's not  soldering Way  at all. ?!!!

    You just attached the aluminium  pieces  by coper wire. And you solder the coper wire .

    So the aluminium pieces are attached but not soldered .

    Anyway you are welcome bro   and have good luck.

    Thank you. Maybe that's a more appropriate name.

    if there's movement (wind , manipulation , vibrations) you might experiment ups and downs in signal strength (VSWR , Mismatch impedance, resonance , etc)

    As long the CONTACT is good , all ok.

    At each plate connection, I put a little wedge which I glued on both sides. So the connection remains secure.

    what i've notice in the SIMs is that every time you add metal Frecuency of Resonance goes up , a little...you might try to take that into account

    PS: is that a SIGN or a LICENSE PLATE...

    If it was made a little neater, would it still affect the resonance? That's right, the material I use is the vehicle number plate / License Plate.

  5. To conclude from the image above, each joint I'm about to solder looks like a small coil of copper wire. The key to making soldering on aluminum easier is the winding of the copper wire. I took this copper wire from a piece of LAN cable. Then, the two plates to be joined, I made holes with a diameter of 1 mm on both sides, then the two holes were joined with a copper wire coil, wrapped as tightly as possible, then just glued the tin with solder on the front and back. I think this is the easiest way to do it.
