Tutorial to create Wireless antenna cans

Do not dispose of cans in your home. Recycling as a cheap wireless antenna gala.

Basic concept of a green lifestyle, ie, reuse, refill and recycle, also applies in the world of information technology. This is evidenced by Muhammad Salahuddien Manggalany or a familiar dipangil Didin or standard. Didin recycle cans into the wireless LAN antenna. Initially the vessel isengiseng as experimental, but now, this business has become a significant new land promised.

In fact here is not an antenna cans utterance is true. For, in the overall antenna cans, only function as a balancing saja.Didin logikanya with helical antenna on the HT is only balancing, not an antenna.

Didin menekuni start a business of making an antenna cans since 2002. Initially, the Didin Bino Utomo do with this, using the tin susu children as experimental material. Unfortunately, when the spectrum analyzer so difficult to search and Bino Didin can not analyze the performance of antenna self-made cans.

They only analyze based on the distance range and connection stability only. While the signaling can not be analyzed without tools. So when it does not obtain data leakage signal, the frequency spletter to another, and so forth.

Slowly, Didin begin to analyze their own based on trial and error. And to find some critical point in making an antenna cans. For example, the antenna is generally cans have emission angle (beamwidth) 15 degrees. This is known to compare with the angle beam antenna signal so.

Didin also utilize the most of the guide-guide on the wireless antenna is in the Internet.Tak Didin rarely find people who are considered experts invited to discuss.

From the results of the trial and error, discussions, try again, experiment, and the guide on the Internet, Didin eventually find a way optimal antenna up cans.

Ways optimal calculation includes ideal, technical installation, pointing to the correct mechanism. Result, the artificial antenna cans Didin diadu with the original wireless antenna.

While techniques have found the ideal antenna assembly cans, things that happen in the Internet world of Indonesia. That is a new trend in service Internet Service Provider (ISP) that provides wireless application start flare. In addition, many ISPs that change with the mission topologinya approach to consumer self. Ie, configuration and network topology wireless LAN outdoor low range with the maximum density.

"That is," continued Didin, "ISP establish Base Transmission Station (BTS) in the vicinity of the concentration of new clients, with low coverage (about 1-2 km) to reach customers who are concentrated in the area."

Engineering Installation
Making your own antenna cans through some stages. The first stage is the making of cans, the antenna itself. Proceed with the installation and pointing. Step by step guide of making an antenna cans included in our special box at the end of this article. Guidelines were created specifically for the Media PC. And by two diperagakan Didin staff, ie, Andi Fauzi Firdaus Noor and Erwan.

There are some things that need to be understood before installation. That is, use the calculation of the Link Budget Calculator http://www.satsig.net/link-budget.htm. And to calculations using a site survey, site http://www.cplus.org/rmw/english1.html.

Once installed and already in-pointing, the antenna gain compared with the wave guide antenna existing links that already exist. Place the antenna on the tower or pipe pointing up and do a maximum and is ready for use.

Do not forget, look at the weather for the safety and the radio antenna. Do not ever do when pointing gloomy, let alone rain. Whether on location or at the ISP who want dituju. However, the wave LAN antenna, either canned or original, is still sensitive to the weather.

Various Forms of Different way
There are radio devices that already have a mini-hub in it. As Iconnect product. However, there are still regular konektornya UTP, such as products Compex, Senao, Planet, and others.

For devices that already have a radio mini-mini-hub or router or NAT gateway, can be mounted directly to a user's computer, without passing through the router again. However, if the model of radio devices installed are still common type of bridging, the router is required. Especially if the connection would be to share some of the client.

However, if only for a single user, can be installed directly through the ethernet card. According Didin, ISP in Indonesia generally choose products that already have a router or NAT gateway. Because, much easier than setting or its setting, topologinya also more flexible.

Once ready to install, pointing to the live signal from the ISP. According Didin, the antenna is already built in this way can reach 1 to 2 km.

Untung Wafer
Unfortunately, that also Didin into the Council presidium IndoWLI (pegiat community wireless Indonesia) is not interested in the business as an antenna container business in large scale. With entengnya, Didin confess that he often only cans antenna gain wafer form which would be eaten kalengnya as the main material used as an antenna.

Business instinct Didin low, because they appear idealist. According Didin, "Make cans antenna is basically just an experiment and hobby. In addition to encourage people to be smart. "Didin, particularly in the provision of services making the antenna cans, in fact serve only the users who like to experiment, not purely commercial. And processing costs are disebutnya as "the cost of idleness" who does not own or want to experiment still afraid to take the risk of radio equipment.

Often times people come to Didin bring their own material. Didin in place, they borrow the equipment is relatively complete and ask for supervision only. Isn'T receive a fee, even more often Didin must provide to treat the guests like this. But he would not mind. For, as this type of clients are students and most of my friends own.

To the future, Didin not expect much from the business operation is very prospective. The man who was still studying at the Graduate University of Muhammadiyah Malang, only hope more and more people dare to try and use home-made antenna. In business, Didin many receive income from the sale of the original antenna. Moreover, Cross-sky company management also became a reseller several antenna product imports. Both from Europe, China, or Taiwan. However, the name is well known as Didin perakit antenna cans rather than as a reseller
import antenna.

Didin also serve a lot of demand orders from outside the city, even outside the island. When interviewed, Didin middle antenna cans to make some order from the user in Pontianak and Pekan Baru.

Even in the event, many Internet cafés to use antenna Didin cans made to save investment device. Public Internet use cans for antenna related to the ISP, or connect several Internet cafés in a group. Almost all of the ISP, that if the client does not object to using an antenna cans. For, the most important is the connection, not physical.

So now there are two options for us. Membisniskan antenna cans, or users. Clear, we know now, why so many cans and susu wafer above the neighboring houses.
