OTA multipath profile
The Multipath Profile enables you to determine RF environmental conditions of testing
area. It indicates the amount of power of the dominant pilot signal that is dispersed
outside the main correlation peak due to multipath echoes that are expressed in dB.
This value should be very small ideally.
The multipath profile is the result of portions of the original broadcast signal arriving at
the receiving antenna out of phase. This can be caused by the signal being reflected
off objects such as buildings or being refracted through the atmosphere differently
from the main signal.
