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 :

omni colinear wifi antenna for 2.4ghz

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.

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 :

Frequency Range 802.11a: 4.9 ~ 5.875GHz
802.11b/g: 2.4 ~ 2.5GHz
Gain 802.11a:7dBi
802.11b/g:5dBi
VSWR 2.0:1
Polarization Linear, vertical
HPBW/ Horizontal 360°
HPBW/ Vertical 802.11a:25° 802.11b/g: 35°

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.
