Membuat antenna omni

mungkin sudah banyak ditemukan di url2, ane hanya menyoba dengan menyadur ulang, plus pengalaman2 sendiri....

bahan

  • 1 meter kabel RG 213 yg mempunyai faktor velocity = 0.66
  • pipa paralon 1 inchi ama dop nya
  • N female connector
  • Lem pipa

alat

  • tang crimping
  • cutter
  • solder + timah
  • garisan
  • gergaji besi

mari menghitung

                 V * C    0.66 * 299792458
1/2 wavelength = ------ = ---------------- = 0.0405m = 40.5mm
                 2 * F     2 * 2441000000
                     
V = Velocity Factor   of  RG213  = 0.66
C = speed of light = 299792458
F = Freq  = 2441000000 (tengah2 nya 2.4ghz )

nah kalo mo ganti RG213nya, berarti beda lagi itungannya, tergantung jenis kabel yg digunakan...
