Has anybody tinkered with making their own external antenna for connection to the Nanostation - to extend signal range?
Can you post experiences/blog/diagrams- if any

First off, the Nano 2 has a 2 dB loss to the antenna port due to circuit board trace loss. Almost 5 db with the Nano 5. That means your antenna would have to be at least 16 dBi gain to equal the gain of the internal antenna.
[Edited - That means your antenna would have to be at least *TWELVE* dBi gain to equal the gain of the internal antenna *OF THE NANO 2*.
Second, you have to have 6 dB gain to double your distance.
So now you're looking at a 22 dBi gain antenna.
[Edited - So now you're looking at a *EIGHTEEN* dBi gain antenna *FOR THE NANO 2*.
That would require some very tight tolerances and without a $1,000 SWR meter, you won't know if your antenna construction is correct.
Commercial 22 dBi antennas usually cost under $40.
Well engineered projects are indistinguishable from crazy ideas.
Speed, distance, reliability, cost...Pick three.

BUT.. if you really want to build one because its expensive in your country or you just want to try it. then here's the link for lots of 2.4Ghz antenna projects. Go to the middle of the long page for the Amos sector antennas (Awsome!)
This thing is so addictive. Im preparing materials for Amos 9 sector antenna. ;-)
