    I think this is a pretty common thing to do. Lots of point to point wifi links use dual polarisation antennas. In fact it can actually be the same antenna so long as it has good isolation between the ports.This antenna does not have this... S12, S21 must be> 30

    Be careful, port to port isolation is not the same as polarization isolation. Polarization isolation is a useful technique when you want to transit two simultaneous signals and both can exist. It is like transmitting on vertical and horizontally polarized antennas.

    If you are transmitting through a Wilkinson to two antennas (one RHCP and the other LHCP) you could be in for some interesting effects. The resulting polarization will depend on the rotational orientation of each antenna and any additional phase difference in the feed lines. You will end up with some elliptical polarization with the axial ratio and major axis probably in an unexpected direction. Sorting out what you have will be fun.

     

    THE BEST IS THAT...

    I am interested in this model, please share the actual size that has been tried and working
