Appendix F Antenna Guidelines
WARNING!
Antennas and associated transmission cable must be
installed by qualified personnel, and external antennas must
be properly grounded. WaveRider assumes no liability for
failure to adhere to this recommendation or to recognized
general safety precautions.
The CCU and EUM have been certified for use with Omni, Patch, Yagi, and Dipole Reflector
antenna types, in addition to the WaveRider Diversity Antenna. Table 46 includes examples of
each of the recommended antenna types, as well as their associated maximum antenna
gains.
Table 46 CCU, EUM Supported Antennas
Antenna system gain is the net gain of the system. In other words, it is the antenna gain minus
the insertion loss due to cabling, connectors, filters, surge protectors, and other hardware
components. During installation, you must verify that the antenna system does not exceed the
maximum allowable certified antenna system gain, which is 8.8 dBi.
Calculate the antenna system gain by adding the value of the insertion loss for each
component of the antenna system, excluding the antenna, and subtracting the total of that
sum from the antenna gain. You can measure the insertion loss of the components, and the
Antenna Type Maximum Antenna Gain
Omni 5.1dBi
Patch 8.5dBi
Yagi 13.0dBi
Panel 12.0dBi
