10 $ WIFI 16dBi Super Antenna Pictorial

Step 2Mount the BNC connector to the plate

Find the center of the plate by drawing lines between the corners and make a mark 20mm from the center. Drill a hole in the plate at that point that is big enough to fit the center conductor and its isolation. After drilling, you can put the connector in the whole, mark the 4 fixing holes, drill them and mount the connector using small bolts.

I am building this one again.
I wanted a way to mount the plate & aim it
a refinement I opted for is to put a .060" aluminum 2"x12" bracket in between the Copper plate & the N-50 connector. drilled & used a countersink bit to bed it in till solidly placed.
bend the ends 90 degrees. drill holes as needed & mount.
I am planning on getting a Students gooseneck lamp & mounting my antenna in place of the lamp.
this extra metal has a benifit of keeping the soldering nub/hub down below the surface.
just trimmed the soldered part down to 1 mm high.

Well, if you're truly going for the absolute best, then I would have to say use Gold.

He's kindof right, but a more affordable option is copper (the best), or brass, or aluminum. Only use steel if you have to.

What exactly is this Brass for? Right now I see it as a base. But the way you see it might be more complex. I would like to learn this.

The brass plate is acting as the reflector / ground plane part of the antenna. For more information on this and other styles of antennas I suggest using your favourite search engine and look for "antenna radio design" as staring keywords. Also check your library for back issues of amateur radio antenna design and cook-books. they have all the math and theory in them reduced into digestible and understandable chunks. Also check out the ARRL and other HAM radio user sites. Lots of their stuff is adaptable to wifi since wifi is mech smaller and easier to play with than short wave.
