Antenna Alignment
When aligning the antenna you should examine the physical environment where the
equipment is being installed.
Check for obstructions, available mounting locations, and other factors.
Things such as trees, buildings, and hills, can obstruct the antenna, reducing the
signal strength.
The antenna should be installed at a height above such obstructions, and aligned so
that antennas are directed at each other by taking into account the horizontal angle
and the vertical angle of the antenna signal.
When the antenna is at the optimum alignment, there is less possibility of
encountering interference and of causing interference.
The radios work best when they have line-of-sight. If the radios do not have
line-of-sight then you will get a very poor signal or no signal at all.
If the radios are not aligned correctly the signal quality of the radios will suffer and
you may not receive the throughput you require.
