Nueva WIFI Antena Panel de 21 dBi’s

Monday, December 21st, 2009

Hi.

There is new panel antenna on zero wireless site – I am posting images and links to the posts.

Please if anyone have bigger and more quality pictures post them as comment here.

Thanks.

It is real wifi antenna on the first picture – there is not so mush antennas with such amplification so it will be easy to find the model of this one. Will be interesting to see antenna specification and diagram.
