I think now the new antenna for it to bloom so that many pan or known by Wajanbolic. With Wajanbolic, we get free internet access (*), and making this antenna seems Wajanbolic’ve much to discuss. Btw never mind I’m serving this at my blog, for rekan2 who had not received the information but want to make. (*) Obtained with free Internet take / shot hotspot network is still accessible to reach with Wajanbolic. if we get these hotspots deh … … Free Internet … … Good luck …
BACKGROUND
- To increase the range of wireless LAN is required an external antenna with a gain higher than the standard antenna
- High gain external antenna relatively high price
- Many items that are often encountered in everyday life that can be used to create the High Gain Antenna with easy and low cost.
PURPOSE
* Sharing knowledge / experience in making homebrew antennas Antenna Wajanbolic and especially the things about Wireless Network
SCOPE
In this workshop will be made Wajanbolic Antenna with N Connector and Pigtail
FLASH WIRELESS / WiFi
WiFi (Wireless Fidelity) is a generic term for equipment or WLAN Wireless Lan. Regular use IEEE 802.11 standards family. Therefore, many vendors are supported.
STANDARD PROTOCOL
Wireless equipment commonly used is to use IEEE 802.11x.
BASIC LAW
Minister Decree No.2 of 2005 on the use of frequency bands 2400-2483.5MHz which was signed on 5 January 2005 Minister of Transportation aleh M. Hatta Rajasa.
Some things are important from Minister Decree No. 2 of 2005 is that you do not need permission from the government radio station to run the internet equipment at 2.4GHz, but limited to:
1. The maximum transmitter power is 100mW (20dBm).
2. Effective Isotropic Radiated Power / EIRP 36dBm at the antenna is
3. All equipment used must be approve / certified by the POSTEL
Antena Wajanbolic
Why is Wajanbolic?
* Frying Pan: pans, kitchen utensils for cooking
* Bolic: parabolic
* Wajanbolic: parabolic antenna-made from the pan
Because it comes from the pan does not match his perfection dg virtual parabolic antenna. In the workshops will be made Wajanbolic Antenna with N Connector and Pigtail with consideration:
Some shortcomings antenna Wajanbolic:
Because of the influence of solid dish large enough wind to warrant mounting to a tower that is strong enough
2.4 GHz ANTENNA
Some Examples of 2.4 GHz Antenna Design
Most homebrew wifi antenna imaginable on the Internet: yagi antenna, antenna can (tincan antenna), biquad antenna, helix antenna, antenna Slotted Waveguide. Components yg always be on the antenna-antenna design tsb: N-type Connector & Pigtail
Connector: N-type Male, Female N-type, RP TNC Male, RP TNC Female, Pigtail
Ok ..!! we go directly to the creation Wajanbolic
Preparation
Equipment and materials necessary in preparing:
MATERIALS
1. Pan diameter 36? (diametr bigger the better)
2. Thin paralon diameter PVC 3? 1 meter
3. Doff 3? (close paralon PVC) 2 pieces
4. Aluminum foil
5. Bolt + nut size 12 or 14
6. Connector N female
7. copper wire no.3
8. Double-sided tape + tape
EQUIPMENT
1. Ruler
2. Knife / Cutter
3. His + tin solder
4. Hacksaw
ESTIMATED PRICE
Estimated cost incurred to purchase Wajanbolic material is less than Rp 100,000, -. Compare presented you should buy 24db Grid Antenna, a homemade local only Rp 500,000, – more, and that imports could reach Rp 1.000.000, – more. Or buy local grid antenna that her price Rp 200.000, – while the imports could reach Rp 300,000 more.
STAGE workmanship
1. Prepare all the ingredients and equipment needed.
2. Punch a hole right in the middle of frying pans are the size of bolts 12 or 14, just one hole only.
Later, measuring diametr pan, deep frying pan and feeder / point of focus. For more details please see his picture below.
Example:
Parabolic dish dg D = 70 cm, d = 20 cm the distance from the center focus point dish: F = D ^ 2 / (16 * d) = 70 ^ 2 / (16 * 20) = 15.3 cm
At that point they will focus on the end of the feeder installed. To get the maximum gain.
1. Cut the PVC 30 cm long paralon, then give a sign to her feeder distance (region-free aluminum foil). To determine its long-feeder use the formula above.
2. Make a hole in the paralon to put N Connector, for the antenna can use the formula. Bias in view of http://www.saunalahti.fi/elepal/antenna2calc.php
3. Cut the copper wire that had been prepared in accordance with the size of the calculation results obtained from the website above. And the N Connector solderkan have prepared
4. His next, paralon with PVC wrap with aluminum foil on the area other than feeder, klo existing aluminum foil without glue, then glue them to be able to use double-sided tape
5. N connector, then attach it to the PVC that has been hollowed Paralon td
6. In the doff (paralon PVC lid) that will be installed at the end near the N Connector must give aluminum foil, while the doff of the pairs in the pan does not need to put aluminum foil
7. And attach it to doff PVC paralon
8. Then, the pan that has been in bolongi was paired with a doff of his again, before it is drilled doff according to the size of bautyang been prepared, and tighten it secukup.
9. Then attach PVC lived paralon had to skillet doff already in pairs.
10. Wok Bolic and is ready for use when browsing, or at least not for wardriving.

waaah iini sih agak pusing, tapi anda bisa lihat di web saya cara nyantai dan menyenang kan bro
#2 by aan on July 10th, 2008
wah kalo bisa saya dibuatkan satu masss, soalnya di samping kios saya ada hotpot meski harus bayar seribu perjam tapi gpp. tolong ya mass nek isa..
makasih…. ntar usb wifi tak beli sendiri gpp
#3 by zigun on July 10th, 2008
sebenernya gampang kok buatnya! bahannya juga gampang didapet, cuman kmrn yg agak susah cari alumunium foilnya!
btw cukup handal lho nih wajan bolic.
dari 5 AP yg detect bisa sampai hampir 50 AP yg kedeteck. ckckckckckc…

kang, cara nyambung kabel belden dgn kabel usb gimana kang, tlg dong info spesifikasi kabel nya,thx
salam kenal..
#5 by zigun on July 17th, 2008
nyambung kabel mah gampang kang iwan! Lihat dulu USB isinyanya ada berapa, soalnya ada yg isi 4 dan kadang ada yg isi 5.
Kalo isi 4, kabel UTP kan ada isinya 8 bagi 4 aja, masing2 2 kabel.
Nyambungnya USB dgn UTP sesuaikan warna Ujung 1 dengan warna ujung yg lain sama.
Misal bila Ujung USB kabel merah sambung dengan 2 kabel UTP warna apa aja, ujung lain juga harus dpt kabel warna yg sama dgn USB dan UTP.
Gmn? Bingung ya!…

Trims buat informasinya!!!
#7 by gue on August 10th, 2008
mau nanya nie… setelah proses yang panjang akhirnya terdeteklah satu sinyal (ntah apalah itu) yang pasti pas diliat signalnya itu 100%.. yang masalahnya pas di klik “conect” ternyata tetap gak bisa dijalankan pas aq liat di network conectionnya itu ada gambar gembok dan tulisan “not conected” diatas tangga sinyal yang warna ijo itu(penuh)… jadi gimana tuh.. cuma satu itu yang terdetek… satu lagi gak jelas cuma kotak2 tapi sinyalnya juga 100%.. balas ke emailku yah.. rave_yori@yahoo.co.id
#8 by zigun on August 11th, 2008
untuk bisa dapet status connected dari suatu sinyal wifi harus diperhatikan:
1. sinyal itu open atau tidak
2. adakah kode enkripsi seperti WEP/WPA, lha ini yang agak sulit, kita kudu tahu kode ini untuk bisa dapet koneksi dengan sinyal tsb.
3. dan apakah memang sinyak tersebut memang disahring, status DHCP dari server sinyal memang diaktifkan.
4. apalagi ya? kalo ada bisa dong ditambahkan!
#9 by axl on August 13th, 2008
mas kira2 low pake alat ini jarak hotspot yang bakal ke detect brapa kilometer???
soalnya tempat hotspotan dtempatku paling deket -+1km
djawab yaw thanks
#10 by zigun on August 14th, 2008
Jarak ideal daya tangkapnya sampai 2 kilometer, tetapi setelah saya coba, bisa lebih dari 2 kilometer walaupun sinyalnya kurang begitu bagus. Tergantung juga medan antara hotspot dan tempat kita. Jadi kalo 1 kilometer, bisa deh dengan alat ini. Selamat mencoba aja.
Good luck!

ada bos. coba aja masuk ke http://www.jaylangkung.com atau http://rtrw.net/
Semoga membantu.
Thanks udah berkunjung ke blog saya

bos kalo bwt wirelessnya pke wireless router atau wireless access point?soalnya ane punya D-link DWL-G700AP (acces point) kira2 bisa di pake buat nembaknya ga?
#14 by zigun on January 20th, 2009
bisa banget bos!
#15 by paranoid on February 6th, 2009
bos zigun sinyal dah dapet nih nah cara koneknya gimana???
#16 by zigun on February 7th, 2009
ya udah, tinggal klik connect saja! tetapi itu bytuh WEP key atau tidak, biasanya kalau sinyal nya Open alias gratis, tidak perlu WEP. Jadi carilah sinyal yang tidak ada tanda kunci. BAru dicoba dikoneksikan.
#17 by Paranoid on February 10th, 2009
Udh cba d conek tetep g bisa.Sinyalnya sih ga d encrypt bos.D scan pake net stumbler ip &subnet mask nya ga dapet.Apa mgkn AP yg di tuju sedang ga aktif?
#18 by zigun on February 10th, 2009
Mungkin juga tuh. Coba saja cari AP yang kira2 aktif dan memang untuk koneksi internet. Kayak punya warnet atau hotspotan.
#19 by Paranoid on February 10th, 2009
Kalo lihat di net stumbler sih ada 1 AP yg aktif ga di encrypt,grapic signalny jalan di -70,tapi ip&subnet masknya ga dpt coba di conek ttp aja bos ga bisa konek,apa mgkn mac qt msti di rubah pake mac AP tsb?
#20 by zigun on February 10th, 2009
wah susah juga nih kasusnya, soalnya AP ada bermacam-macam setingan security dan filternya. ada yang memakai wep, WPA dan juga memakai filter MAC address. Kalo APnya make yg filter MAC address ini, ini yang susah, hanya MAC adrees yang sudah diseting di APnya saja yang bisa konek. Untuk lenih jelasnya, coba saja masuk ke forumnya RTRW.net saja. Mungkin disana akan mendapatkan solusi dan pemecahannya.
#21 by Ipank on April 6th, 2009
Numpang lewat sekalian kasih komen,
Sekedar berbagi pengalaman. Menanggapi banyak pertanyaan “udah bisa konek tapi dengan menggunakan netstumbler belum dapet IP dan net subnet masknya” itu berarti AP tersebut tidak di setting DHCP sehingga kamu tidak bisa dengan otomatis mendapatkan IP dan subnet masknya. Hal tersebut merupakan salah satu trik pengelola hotspot agar tidak sembarang orang bisa ikutan internetan gratis, jadi yang berlangganan saja yang di beri IP, Subnet mask, IP Gateway dan DNS.
Dan betul kata mas Zigun masih banyak lagi cara untuk melakukan proteksi pada sebuah hotspot.
Solusi:
Bertanyalah pada hotspot sekitar apakah menawarkan paket berlangganan. Karena kamu sudah bisa menangkap signal hotpot yang ada dan kamu sudah menyediakan peralatan biasanya pengelola hotspot memberikan keringanan seperti memotong biaya instalasi dan alat.
Biaya bulanan hotspot biasanya berbeda-beda namun berkisar antara Rp.150-250rb/bulan.
Selamat berinternet.
