Base unitl Dual Sector Antennas installation help please

Hello,

I trying to install a base unit based on:

  • 3 X 120deg 16dbi dual (H/V) MIMO antennas (2.4GHz) (360deg total)
  • 2 X 4 way antennas splitter
  • Ubinquity SR71-12 miniPCI card
  • RB433AH

I need help to get it installed, the main question is which is the best configuration?

my idea is, each antenna has two N-TYPE Outputs (V and H), I am thinking in connecting the V outputs of the 3 antennas to one splitter and the V outputs to another splitter which I will get one cable from V splitter and another from H splitter. each cable will be connected to each chain in Ubinquity SR71-12 miniPCI card. anybody has another solution?

Which polarization should I use for TX and RX, V or H?
