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 :

RFE 2400/90/14

Found on : www.lan23.ru/forum

Antenna specification : LINK

This antenna promises 14dBi but if the pictures below are real I will never believe this.

Very bizarre design ! I never seen something like this. Very interesting also – 4 dipoles /maybe/ and feeding network build by aluminum foil /??? or zing? / . And all this glued with scotch tape?

I do not thing that will cost me 165$ 🙁
