No I had 20-30db SNR on the links when using the slant antenna. The problem was that the radio was not able to differentiate between chains anymore after using the V-H antenna. Now this might be different now that Cambium has firmware which will do Mimo-A where it can down-modulate but at the expense of only being able to use half throughput.
