antenna wajanbolic

why called wajanbolic?

frying pan: wok, cutlery makes ripe

bolic: parabolic

wajanbolic: antenna parabolic yg made from frying pan

because come from frying pan so ill assorted the fullness dg antenna parabolic yg actually. in workshop will be made antenna wajanbolic with n connector and pigtail with deliberation:

several deficits antenna wajanbolic:

because shaped solid menyh so big enough wind influence so that need mounting to tower enough strong

antenna 2.4 ghz

several examples design antenna 2.4 ghz

majority antenna homebrew wifi yg in internet: antenna yagi, antenna can (tincan antenna), antenna biquad, antenna helix, antenna slotted waveguide. component yg always there dlm design antenna-antena that: n-type connector pigtail

konektor: n-type male, n-type female, rp tnc male, rp tnc female, pigtail

ok. . ! ! we are direct to maker wajanbolic

preparation

device and ingredient necessary at prepare:

ingredient

1. diameter frying pan 36? (ever greater mengametr more good)

2. pvc paralon thin diameter 3? 1 meter

3. doff 3? (enclosing pvc paralon) 2 fruit

4. alluminium foil

5. bold + size nut 12 or 146. n connector female

7. copper wire no. 38. double tape + lakban

device

1. ruler

2. knife/ cutter

3. solder + his tin

4. hacksaw

price estimate

price estimate that taked to buy ingredient wajanbolic less than rp 100.000, -. compare ji you must buy antenna grid 24db, product local achieve rp 500.000, - more and import can achieve rp 1.000.000, - more. or buy antenna grid local his price rp 200.000, - while import can achieve rp 300.000 more.

working stage

1. prepare all ingredients and device that wanted.

2. make hole correct frying pan in the middle of frying pan seukuran bold 12 or 14, enough one hole.

kemudia, ukur mengametr frying pan, frying pan depth and feeder/ points focus. to be more clear he is please tough be picture.

example:

parabolic menyh dg d = 70 cm, d = 20 cm so points distance focus from center menyh: f = d^2/(16*d) = 70^2 / (16*20) = 15.3 cm

in points focus that installed end feeder. to get gain maximum.

1. cut pvc paralon along 30 cm, then say the word for distance feeder he (is alluminium free region foil). to determine long feeder he uses formula above.

2. give hole in part paralon to put n connector, for that use formula antenna can. refraction at see in http: /www. saunalahti. fi/elepal/antenna2calc. php

3. cut copper wire that prepared as according to size that got from calculation result website above. and solder in n connector that at prepare

4. as advanced as he, package pvc paralon with dgn alluminium foil in region besides feeder, klo alluminium foil existing without glue, so for agglutinative he can use double tape

5. then pair n connector to pvc paralon that burrowed td

6. in part doff (enclosing pvc paralon) that at pair at the end of close to n connector must at give alluminium foil, while doff at pair in unnecessary frying pan at gives alluminium foil

7. and pair doff to pvc paralon

8. then, frying pan that at perforate a while ago installed with doff one he again, before he is doff burrowed as according to size bautyang at prepare, and tighten secukup he.

9. then live to pair pvc paralon a while ago to frying pan that at pair doff.

10. and frying pan bolic ready for used browsing, or at least to wardriving.
