Elevation TX cutoff versus VSAT modem bandwidth and power
1. At Elevation TX cutoff enter the minimum elevation angle for the antenna to
function in accordance with ETSI (ETSI EN 302 340) and FCC (FCC §25.205)
regulations.
FCC (FCC §25.205): 5 degrees
ETSI (ETSI EN 302 340): The minimum elevation angle depends on the Tx
bandwidth and the nominal power of the VSAT modem, see the table below.
