Recommendations
The NCL1170 has been certified for use with Omni, Patch, Yagi, and Dish antenna types. The
table below includes examples of each of the recommended antenna types, as well as their
associated maximum antenna system gain.
Table 11 NCL1170 Supported Antennas
NOTE: For a Dish antenna a cavity filter with a minimum rejection of 20
dB ± 22MHz from the channel center frequency is required.
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, filters, surge protectors, and other hardware components.
During installation, you must verify that the antenna system does not exceed the maximum
allowable antenna system gain for that specific antenna type.
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 gain, at the frequency of interest, or obtain it by referencing the manufacturer’s
supplied literature.
