• Wajan : frying pan, kitchen tools for cooking
• Bolic : parabolic
• WajanBolic : a parabolic antenna-made from the pan

MATERIALS

1. Pan, diameter 36 “(the bigger diameter is better )
2. Thin PVC pipe with diameter, 3 “1-meter
3. Doff 3 “(PVC pipe cap) 2 pieces
4. Aluminum foil
5. Nut bolt 12 or 14 size
6. N Female Connector
7. Rule 3 copper wire
8. Double tape duct tape
EQUIPMENT
1. Ruler
2. Knife / Cutter
3. Solder tin his
4. Hacksaw
ESTIMATED COST
Estimated cost incurred to buy the materials for WajanBolic is less than USD $10-. Compare when you have to buy24db Grid Antenna, the local homemade alone reached USD $50 to hundreds.
STAGES
1. Prepare all ingredients and equipment needed.
2. Punch a hole right in the middle of frying pan the size of a bolt 12 or 14, just one hole only.
Then, measuries diameter of pan, deep skillet and feeder / focus point. For more details please see his picture below.

Example:
Parabolic dish dg D = 70 cm, d = 20 cm so that the distance from the center focus point dish: F = D ^ 2 / (16 * d) = 70 ^ 2 / (16 * 20) = 15.3 cm
At the focus point mounted an edge feeder. To get the maximum gain.
1. Cut the PVC pipe with 30 cm width, then mark for its feeder distance (foil-free areas). In order to determine its long-feeders use the formula above.
2. Give hole in the pipe to put N Connector, for that use antennas formula cans. You can visit 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. Solder it on N Connector that has been prepared.
4. Next, wrap PVC pipe with aluminum foil on the area in except the feeder.
5. Attach the N connector to the PVC that has been hollowed.
6. In doff (PVC pipe cap) which will be installed on the tip near the N Connector must be given aluminum foil, while the doff of the pairs in the pan does not need to be given the aluminum foil
7. And attach the doff to the PVC pipe
8. Then, attach the other doff with other pan that has been holed once again, before that hole the doff sized with bolt that already prepared, and tighten it.
9. Then attach PVC pipe lives into a pan with doff attached.
10. And WajanBolic is ready for use for browsing, or at least for wardriving.
