estqwerty’s wifi antennas

Multipolarized antenna from wifi plus.

Blueprint is found on www.zero13wireless.net/forum visit site for more info and pictures.

Specification and pictures of the original antenna :

• Compact Omni head design
• Dual Band Frequency
• Beamwidth: 360° Horizontal, 15° Vertical
• Quad Stack improves gain to 12dBi
• 7° downtilt for height installation
• Includes pole mount bracket for mast mounting up to 1.625″ O.D.

It is surprising that they give this antenna as dual band?

So this is the top omni model of this kind of antennas.

And I can’t find it on site - so it seems that it is not manufactured anymore.

Here is the scans of inside - very thin pcb board is used.

Some time ago I needed some 5ghz antennas - this is the first thing that I bought.

Dual-band 11a/g 7/5dBi Indoor Omni Antenna from trendnet.

The papers says :

The stupid thing is that on the site specification and in pdf data sheets was said that this antenna have VERTICAL polarization, but now I can see that omnidirectional pattern came whit horizontal polarization!

This may be the reason why I am not happy whit this wifi antenna and it is still laying on my desk.
I will test it again when I have some time.

The other small wifi antenna that I have from trendnet is working great - I have small 5ghz link whit it - these days maybe will scan ti too.
