I had order it
http://www.ebay.com/itm/New-Dual-Band-2-4-5-8Ghz-9dBi-RP-SMA-High-Gain-Antenna-/130729553117
on Sunday and I'm going to return it back tomorrow.
Why? It's easy to explain. Even on 2.4 band stock antennas work better.
On 5GHz this "Dual Band High Gain" antenna doesn't work at all !!!
O.K. At the first I ask myself - May be the antennas very sharp directional?
I put router on the floor and walk around inside room and outside to house,
went up to the second floor and gone down to basement,
to try to find the maximum and minimum points...
I was trying to change positions of antennas of router and turn my laptop right-left, up-down... l lift and put laptop on the floor.
Of course I saw changes on inSSDer and they were different in different places.
BUT almost always worse or same like with stock antennas.
I couldn't believe... I don't want believe to it...
I walked around same way and did measure the level of signal in same points
three times for 2.4 and two times for 5GHz band and wrote down the figures...
And with each next time I was more and more sure that my new "double-band-high gain antennas"
ARE "not-double-band-not-high-gain" and only chip chines fake.
OK.
It's only MY my results.
And I really very hope, that others have good experience with this.
And may be the reason for such terrible results only personal myself.
P.S. I had conversation with seller and asked him about the model etc.
he told me that he has information from his diller and if I want I can return this antennas back
any time.
I knew the risk =chines+chip+no name of model+no name of manufacturer+no any warranty...
That experience cost for me a several dollars for shipping.
P.P.S I have two antennas
