Bolic Pan..

Tips - tips pan bolic

To increase the distance range of wireless LAN antenna required with external gain a higher standard of antenna

  • external High Gain Antenna price relative expensive
  • Many items that are frequently found in everyday life that can be used to make the High Gain antenna in a way easy and cost light

    PURPOSE

    • Sharing knowledge / experience in terms of making homebrew antenna Antenna WajanBolic and especially the things about the Wireless Network

      SCOPE

      In this Workshop akan WajanBolic made with Antenna Connector and Pigtail N

      overview WIRELESS / WiFi

      < span style = "font-size: 85%;"> WiFi (Wireless Fidelity) is a generic term for equipment or WLAN Wireless Lan. Normal family use the standard IEEE 802.11. Therefore supported by many vendors.

      BASIC LAW

      Minister Decree No.2, 2005 about the use of the frequency band 2400-2483.5MHz who signed on 5 January 2005 the Minister of Transportation aleh M. Hatta Rajasa.

      Some of the important decision of the Minister of No .2 in 2005 is that you do not need permission from the government radio station to run the equipment at 2.4GHz frequency, but is limited to the:

      1st Maximum transmitter power is 100mW (20dBm).

      2nd Effective Isotropic Radiated Power / EIRP in antenna is 36dBm

      3. All equipment used must be approve / certified by POSTEL

      Why is WajanBolic?

      • pan: frying pan, kitchen tools make cooking
      • Bolic: parabolic
      • WajanBolic: parabolic antenna made from the pan

        Because it comes from the frying pan kesempurnaannya not comparable dg parabolic antenna factual. In the workshop will be made WajanBolic Antenna with N Connector and Pigtail with:



        Some of the lack of antenna WajanBolic:

        Because solid form of the influence of wind dish large enough so that require mounting to a tower strong enough

        Some Antenna Design Example 2.4 GHz

        Most homebrew wifi antenna you have on the internet: yagi antenna, antenna cans (tincan antenna), antenna biquad, Helix antenna, slotted waveguide antenna. I always have the components in the antenna-design antenna page: N-type Connector & pigtail

        Connector: N-type Male, Female N-type, RP TNC Male, RP TNC Female, Pigtail

        Ok ..! we go to the making of WajanBolic

        Preparation

        Tools and materials that need to prepare in:

        MATERIAL

        1. pan diameter 36 "(the bigger the better diametr )
        2. PVC paralon thin diameter 3 "1 meter
        3. Doff 3 "(closed paralon PVC) 2 pieces
        4. aluminum foil
        5. Baut + mur size 12 or 14
        6. Connector N female
        7. copper wire No.3
        8. Double tape + lakban

          EQUIPMENT

          1. ruler
          2. knife / Cutter
          3. its tin solder +
          4. hacksaw

            estimates RATES

            < strong>

            < strong>

            Estimated price spent to purchase materials WajanBolic is less than Rp 100.000, -. Compare jikan you have to buy Grid 24db antenna, the only local product to Rp 500,000, - more and import could reach Rp 1.000.000, - more. Antenna or purchase price of the local grid is Rp 200,000, - while the import could reach Rp 300,000 more.

            development

            1. Prepare all materials and equipment needed.
            2. Lubangi pan right in the middle of the frying pan seukuran bolts 12 or 14, just one hole only.

              Then, measure diametr frying pan, frying pan depth and feeder / focus point. For more details please his tough image below.

              Example:

              parabolic dish dg D = 70 cm, d = 20 cm the distance from the center point focus dish: F = D ^ 2 / (16 * d) = 70 ^ 2 / (16 * 20) = 15.3 cm

              page focus on the point end of the feeder is installed. To get the maximum gain.

              1. Cut PVC paralon along 30 cm, and marked for its feeder distance (region-free aluminum foil). To determine the length of its feeder use the formula above.
              2. its hole in the paralon N Connector to place, to use the antenna formula cans. See bias in the http://www.saunalahti. fi/elepal/antenna2calc.php
              3. Cut copper wires that have been prepared in accordance with the size of the calculation results obtained from the website above. And solderkan on N Connector that has been prepared in the
              4. Selanjut it, wrapped with PVC paralon with aluminum foil on regions other than the feeder, I have the aluminum foil without glue, to paste it can use the double-tape
              5. Then pair with N connector to the PVC Paralon has dilubangi td
              6. At the doff (closed paralon PVC), which akan in pairs on the edge near the N Connector must give in aluminum foil, and doff the tide in the pan does not need to give it in aluminum foil
              7. And the pair are to doff PVC paralon
              8. Then, the pan was Mentioned in bolongi paired with a doff of his again, before its doff these dilubangi according to the size bautyang already prepared in, and tighten its secukup.
              9. Then live pair PVC paralon before frying pan to the pair already in the doff.
              10. And bolic pan is ready to be used for browsing, or at least for wardriving. < / li>
