5. Antennas are intentional radiators and can couple energy into other PIM generating
structures in close proximity. Depending on the level of PIM generation within the
adjacent structure the PIM can, in turn, also be received by the antenna and then be
measured by the Test Set. In this case it is difficult to know if it is the antenna at fault
or if the PIM is due to the environment around it.
