EAR Controlled - ECCN EAR99
ZONE 1 named “Fwd Deckhouse” begins (
REL Start
) at 334 degrees Relative and ends (
REL Stop
) at
026 degrees Relative. Enter
REL Start
value of 334.0 and
REL Stop
value of 26.0. In this case the mast height only
causes blockage up to an elevation of 40 degrees, so we
set
EL
to 40.0. If the antenna is between these two AZ
Limit points but not in the “mast” zone AND the elevation
is greater than 40 degrees, the antenna will no longer be
blocked.
ZONE 2 named “Mast” begins (
REL Start ) at 352 degrees
Relative and ends ( REL Stop ) at 008 degrees Relative.
Enter
REL Start
value of 352.0 and
REL Stop
value of 8.0.
In this case the mast height only causes blockage up to an elevation of 70 degrees, so we set
EL
to 70.0.
If the antenna is between these two AZ Limit points but the elevation is greater than 70 degrees, the
antenna will no longer be blocked.
ZONE 3 named “Aft Deckhouse” begins (
REL Start
) at 155 degrees Relative and ends (
REL Stop
) at 205
degrees Relative. Enter
REL Start
value of 155.0 and
REL Stop
value of 205.0. In this case the aft
deckhouse height only causes blockage up to an elevation of 30 degrees, so we set
EL
to 30.0. If the
antenna is between these two AZ Limit points but the elevation is greater than 30 degrees, the antenna
will no longer be blocked.
ZONE 4 named “Stack” begins (
REL Start
) at 173 degrees Relative and ends (
REL Stop
) at 187 degrees
Relative. Enter REL Start value of 173.0 and REL Stop value of 187.0. In this case the stack height only
causes blockage up to an elevation of 55 degrees, so we set EL to 55.0. If the antenna is between these
two AZ Limit points but the elevation is greater than 40 degrees, the antenna will no longer be blocked.
