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...
