It also allows you to access WiFi from public hotspots. But keep in mind correct positioning of the mount and aiming are going to be much much trickier. The IdeaWorks long distance WiFi antenna features water-resistant and corrosion-resistant housing so you can mount the antenna indoors or outdoors and not experience interruptions in your connection.

If you want more gain in a cheap setup, then just mount a usb adapter (again preferably one with a rubber ducky antenna) to an old discarded satellite dish. The most basic antenna, the quarter wave, radiates and receives in all directions around (assuming vertical) and has a vertical directionality that is from mostly horizontal (actually best is a bit above) to about 45 degrees (not much goes up) This is basic instructions on building a handmade Double BiQuad antenna for WiFi/WLAN 2.4 GHz with 14. Make sure the leads don't get shorted out. I would mount it to the back of the reflector in a water proof box like you proposed (silicon sealant should be enough to hold it) and solder short leads from the feedpoint to the SMA connector. The Rosewill one I got from Newegg has quite good range. Ive gotten those for as low as $ 7 on sale. I would use a usb adapter that has a rubber ducky SMA antenna on it.

The simple bi-quad also has a very nice bubble radiation pattern to it making it very easy to aim, along with its 10 - 11 dbi in gain, which is enough for most purposes. If I were you, I would just build the simple bi-quad, the double bi-quad is much harder to tweak out. The way I have it connected to my pci wifi card is via a cheap low loss SMA cable extender, but the usb method will give you greater distance. I use it to connect to my garage about 200 ft away, but can also pick up the neighbors wifi from about 800 ft. I built my bi-quad a few years back and the trickiest thing to tweak on it for max gain was adjusting the feedpoint gap, which I did in real time using Netstumbler. A bigger gain difference will be noticed by the element material, so use copper which is a better conductor and is also easier to work with.ĭragoslav Dobricic also has dozens of various 4nec2 models of various wifi antennas, just google. I found this Bi-Quad antenna calculator which will be useful: Ĭlick to expand.As far as common metals used for the reflector, ie galvanized steel, aluminum or copper, the gain difference between them is too miniscule to measure.

I could just run a power cable to the antenna and an Ethernet cable in return.possibly just a patch cable into another AP which would create an all-in-one high gain repeater unit. It would be nice to use an AP in reverse because of the radio strength and on-board NIC it would completely skip the bridge from USB>PC>NIC with a wifi adapter as in my cantenna. However this is used to reverse to beacon out wifi signal as an AP.the great debate of whether an AP/wireless router has a stronger radio than the majority of wifi cards and adapters is still on my mind. ^ It appears to be a Dlink900 access point/wireless router, you can see where the lead to the antenna connector standoff was cut and run up to that Bi-Quad printed board. If I could get some confirmations on reflector metal types and antenna shapes I would like to build something along the lines of this little box here:
