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 :

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.

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.

We waiting for the first test.

On the www.lan23.ru are updated page for building wifi swr meter. mcWit was able to find replacement of the BAT62-03W Schottky diode used by pe2er.nl in his design. New diode is hsms-2822

There are several changes in the elements in due diode change. I can’t understand everything written on the site. But everything is there and all is build and tested.

Now just need to wait for more documentation.

Here is a picture of the finished device :
