I see lots of satellite dishes laying in trash when driving. Antenna WIFI BiQuad Lantenna a doppio quad per comunicazioni wireless a 2.45GHz è di semplice costruzione ma molto efficiente Segnate sul tondino ogni 29 mm in modo da sapere esattamente da dove iniziare a piegare.

We read in the text that the polar plots of normalized gain are obtained with the help of the 4NEC2 software. As with the 'circular waveguide antenna' type also on this page it offers a beam-width (in the vertical plane) not far off that required to efficiently illuminate a standard British satellite dish of f/D ratio. Whether there is or is not similarity of this reviews Biquad Antenna section designs with your project, the description specifies the context of the biquad antenna design and shows design drawings and directivity gain graphs. Tests shows that has a gain of around 11-12 dBi, and double Biquad can. A satellite dish is a powerfull signal booster when used in combination with a WiFi biquad antenna. The simple 2.4GHz Double Quad Antenna is a compact and easy to make high performance antenna offering some 14.4dBi gain. Its one of the few good antennas you can use as a feed for dishes, along with Cantenna. Having shown him my kitchen sieve antenna, I’m sure he believes, correctly I admit, that I am a bit of a whacko. 1 Large (76cm) dish with a biquad antenna. Inserted in the male plumbing fitting is a short length of copper pipe to which I will solder the “biquad” element as soon as I receive the coaxial cable I ordered.Īt the rear of the pan I will attach a female 1/2″ copper plumbing fitting, to which I will attach a yet to be designed system for attaching the antenna to some structure on the roof, assuming that my landlord doesn’t object. I drilled a hole in the center of the pan and inserted a 1/2″ male copper plumbing fitting, which I soldered to the pan. Īlas, I have failed in my search for sheet copper and have had to settle for an aluminum kitchen pan for a reflector, despite the corrosion problems associated with joining aluminum and copper. I was inspired in my antenna plans by the information on this web page and this page.

A while back I posted a photo of my kitchen sieve antenna that slightly improved my reception of the signal from my apartment building owner’s wireless internet router three floors above my apartment.Ī few days ago I mentioned that I had decided to build a Double Biquad antenna and that I had been scouring the City for some copper sheet to serves as an antenna reflector. As I have mentioned I have become interested in antennas with which to received WiFi signals.
