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...
