What is the antenna gain for Rukus R300 ?

[tiger_liu]

I found from Rukus R300 datasheet that the physical antenna gain is up to 3dBi per spatial stream. The Rukus R300 has two spatial streams. When calculating EIRP for Rukus R300, should I use 3 dBi or 6 dBi ?

You would want to use 3, the other spatial stream should not be impacting the range of the broadcast.

Does the antenna gain changes depending on the Antenna angle ?

Always

I was told by Rukus expert that I need to add combining gain due to multiple chains in order to calculate EIRP.
