Recommended placement with nonmetal shelf
Try to modify the antenna mounting position, avoid the major lobe of both antenna
overlap, which is also an effective way for high isolation among different antennas,
especially for high directivity antenna.
It might be difficult to find a perfect position to stagger the major lobe for low directivity
antennas, two factors cause this, one is the major lobe is very broad, the other is the
radiation pattern is affected by surroundings sensitively.
For common antenna we often use, most of them belong to low directivity type, we can
put the antennas in a nonmetal shelf, and place antennas in vertical form, not in
horizontal form, which can help to avoid antennas major lobe overlap and make the
isolation bigger in some degree.
