Thanks.

Yes, they are indeed the same. The Cisco, Proxim or whatever is just to attract potential customers.
HOWEVER, the quality of these antenna on ebay is cheap. They will rust in no time and the dbi is not as advertised.

I bought a flat panel antenna that is completely waterproof. It is only 15 dbi but cost me 39 dollars. The dbi is the one advertised and the material to build it is top notch. (radiolabs)

Considering the money and time I have spent builiding cantennas, yagi, omni and biquad antennnas.... I think it is better to buy something made commercially.
