It could be argued that the height of the biquad dipole should be 14 wavelength above the brass sheet.

This connector is where the cable from this antenna connects. It will be an SMA style connector and intended for 50ohm coaxial cable. ![]() If you are using a WiFi router this is where your antenna cable goes and network cable connects to from your pc. If you are using a WiFi card in your pc, this is where your SMA connector will be, which is where your antenna is connected. I can easily connect to a WiFi network 1 mile away with just the antenna that comes in the package. With this antenna hack antenna, I should be able to connect to a WiFi network at least 10mi away. Its very directional and narrow beam but can pick up routers up to 20 miles away. His house is at 1 mile aerial distance and we have pretty good line of sight to each others house. Thats like building a gun without understanding anything of explosives., either its useless, or, deadly. READ A BOOK, E BOOK, MANUAL STOP BEING STUPID HAHAHA -- BTW I aint knocking on you specifically Aaron, more so anyone you were aiming to help with that statement, we should never dumb things down. As for the comment about the distance of the feedhorn being relative to the frequency alignment. In theory you are correct, it would be intensley important had he been transmitting in that frequency range, However I believe he built this for reception only therefore his wrong distance will only result in a lower db gain, however if my calculations are correct he was recieveing a 24 db gain, witch is a very good gain and can result in a much needed distance boost. I would however like to see the gain we might obtain if we shorten the distance of the feedhorn relative to the dish itself, with that being said I shall address those of you who continue to ask were to hookup the other end of the coax on the computer. For those of you using a desktop with an internall pci wifi card, most if not all of these are equiped with an external antenna jack, you should be able to find the right type of coax end that will screw into place on your antenna connector on the back of your computer, most likely at rad shack. For those of you with laptop computers: If you use the internal wifi that comes with the laptop you are most likely out of luck, as only extremely high end laptops will include an external wifi jack with the built in wifi, However if you use a pcmia slot or usb wifi adapter there are some higher end wifi cards available that have an external antenna connector that uses the same connection end as those on the desktop computers therefore that is were you would connect the other end of the coax. I will be building one of these antennas and experimenting with the feedhorn distance, I will be sure to let everyone know how it turns out. The important thing to remember in all of these is to get the measurements right. The 2.4GHz frequency bands require you to use fractions and multiples of the 125mm wavelength. This means 31.25mm (14 wavelength) pops up in the measurements often.
