12dBi MP12 Quad Stacked Omni 2.4/5 GHz Antenna

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 :

Horizontal Polarized Omni

Monday, August 20th, 2007


Horizontal Polarized Omnis are mystery for me 🙂 . Anyone was seen open vertical polarized omni for wifi. Whit horizontal ones there is another story. Except slotted waveguides /these works great/ , but they are really big things.

Here is one idea for horizontal omni or “double helix antenna” :

Mast is used for reflector for for this one. Ant in the internet there is a lot of designs for spiral antenna. Difference here is that is used dual spirals. Coaxial line is hidden inside of the mast, and its look like that feeding point is on the bottom of the antenna.

One more link – there was calculator for this antenna on that treat : http://wireless.com.pt/forum/index.php?topic=15786.0 but now I cant find it.

Thanks to the rt_rex You can find calculator on this site : Omni Helix XLS

I hope that soon we can see some results and tests of this antenna.
