I am an antenna designer and my company Elboxrf manufactures a line of microstrip antennas with N or SMA style coax as connectors for the frequency from 750 MHz up to 6.5 GHz, while custom designs work as high as 12 GHz. Some of antennas have the equipment box for easy integrate a radio card.
Often copied but never duplicated and this post partially shows why.
Our cheapest product TetraAnt 2 08 80 was designed with the same attention like our most expensive antenna TetraAnt Pro 5 60 18 XHV. Both are made of quality materials like the microwave substrate, the radome or the instrument grade N connectors.
Because of the quality of TetraAnt antennas they are excellent choice not only for wireless internet networks, but also for application where remote sensor are used e.g. for Wireless Camera Surveillance Systems
