Friday, December 7th, 2007

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 :

non line of sight 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.

And interesting part :
