How to Make Your Own Cheap Omnidirectional Antenna (Membuat antenna omnidirectional sendiri)

This is what I've found on the net and also I also want to make one,

What we need :
- 1 meter kabel RG 213 with velocity factor = 0.66
- pipe tube 1 inch
- N female connector
- pipe glue / Lem pipa

what we use :
- crimping
- cutter
- solder
- ruler
- sawer (id: gergaji besi)

this how we count it :

Code:

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 = Frequ = 2441000000

we make little pieces like this :


we make 8 pieces ...

This is the pictures :


on each end, we make much longer





we cut the black cover a little,


and we join each pieces like this


we can make this also




and finish all 8 pieces / selesaikan 8 bagian tersebut....

join the N connector with flap for pipe, and do solder to the end of cable, and use flap for pipe in other side
