In other words, if the transmitter uses a vertical antenna, the receiving antenna will detect a stronger signal if it is also vertical. If the transmitting antenna is horizontal, a horizontal receiving antenna will perform best.

At short range, polarity won't make a significant difference to the performance of a Wi-Fi link. Even if the two antennas have different polarity, they will still exchange signals that are strong enough to keep the data moving at full speed. But when you are trying to squeeze every ...
