Effect.of.F9092EY.Application
The radiation pattern of FN110 without F9092EY has weaker areas compared to the ideal. If the communication
partner is located in the direction of a weaker area, the communication quality can be unsatisfactory, and can
result in additional time for the optimization of the installation position. Attaching F9092EY reduces the weaker
areas of radiation pattern and increases the chance of improving communication quality.
Figure 2 illustrates the radiation pattern of FN110 before and after F9092EY applied; using F9092EY smoothens
the radiation pattern.

F9092EY is less effective in “pipe jungles”. In the pipe jungles, the effect of the refl ections from the surrounding
environment is dominant.
