How To Build Your Own Wajanbolic Antenna

for 802.11(b or g) Wireless Networks or other 2.4GHz Applications

by WAJANBOLIC SHOP

All You Need Is Here

Got no dough for a commercial WiFi antenna? Building your Wajanbolic Antenna is easy, just follow these steps :

1. Collect The Part You will need
2. Work it & Assembling
3. Done

Collect The Part

You'll Need :

1. USB Wireless Adapter
2. A Wok! Yes, it's a wok for cooking. Prefer Alumunium and Greater than 40 cm
3. A PVC Pipe, 3" Pipe with Doff
4. Alumunium Tape
5. Nuts & Bolts
6. UTP Belden Original Cable 15 m
7. USB Cable
8. Tools : Drill, Cutter, Forceps, Measuring Tape, Handsaw, Screw Driver, etc

Work It & Assembbling

1. Count

First step we need to count the focus point of the wok.

F=D²/16d

F = Focus

D = Diameter

d = depth

Such as wok with 40 cm diameter and depth 10.5 cm, will be like this :

F = 40²/(16x10.5) Focus point = 9,5238 cm

Then, we need to count pipe length which coated with alumunium tape

This is λ formula for 2.4 GHz :

λ = C/Freq

λ = 3000/2437

For wifi freq we must have:

0.60λ<>> 74cm <>

Insert Into λg Formula :

λg = λ/√1-(λ/1.706D)²

λg = λ/√1-(12.31/1.706x9.017)²

λg = 20.52

L min = 0.75λg

L min = 15.4 cm

Rounded 20 cm for the alumunium coated

2. Process Assembling

Antenna

• Allocate center point of wok diameter, drill it punch hole on it for Nuts & Bolts.


• Allocate center point of Doff PVC Pipe and punch hole on it.


• Set nuts bolt on Doff gathered wit the wok, and


• Cut PVC pipe into 29.5cm length


• Allocate for placing USB hole, and make hole on it with cutter. measure 5.1 cm from the tip of pipe


• Allocate 20 cm from the same tip of the pipe for Alumunium coated and make side border pattern into it


• Coat it with alumunium tape, not for the shorter but the longer lenght border


• Beside PVC pipe, PVC Doff will need to coat with alumunium tape inside of it.


• Your work almost done! Assembly it with the doff which is placed on the wok.


• For the antenna you're done.

Cable

• Okey, we'll need USB Extender more than 5 m! How to make it?


• First, cut the USB Cable as short as possible.


• Here is the schema :


• Red USB Cable <==> Orange + Orange/White UTP Cable


• White USB Cable <==> Green/White UTP Cable


• Green USB Cable <==> Green UTP Cable


• Black USB Cable <==> Others Cable on UTP


• Now you can use USB+UTP Cable for more than 5 m


• Connect it to USB Wireless on the antenna

You're Done!!!

You can use this wireless antenna less than 2 KMs relative.
