Gain
The Gain of a
ViaLiteHD
C-Band Link is generally consistent with frequency in the designated downlink
and uplink bands. Useable gain and performance can be found in a wide range from 500MHz to 8 GHz.
Below is the data for a High Gain link pair (TX=0dB, RX=15dB)

Effect of temperature on gain
The gain of a
ViaLiteHD
C-Band Link generally reduces as temperature increases. The graph below
shows change in RF gain versus the room temperature gain.
