13dbi DIY Omni WIFI Antenna

Sunday, February 15th, 2009

Lets back to main thing – wifi antennas. Its enough hardware for now.

I hate omni antennas – they are pain to be made and to be tuned – it so hard to get one running – it hard even to buy one working.

This omni antenna is strange , I can not get the idea here.

13dbi Omni WIFI Antenna – this must be an Do It Yourself version of HACKED original omnidirectional wifi antenna.

Look interesting but I do not promise anything here.

Materials needed for this DIY antenna :

PVC tube 20 mm,

PVC tube with copper tube inside of it and inner diameter 15mm,

2.5mm copper wire

Here are the pictures :

So this is a quite interesting antenna. This is the first REAL antenna that is similar to this strange picture that circulate on the internet :

omni colinear wifi antenna for 2.4ghz

The dimension did not match but the idea is very similar. quite interesting match really.

There is nothig on the net about this Radproject 2000 or anything about this upper design.
