6012-12W Installation Manual Setup – Blockage & RF Radiation Hazard Zones
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
8 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.

Programming Instructions:
1. To set up the blockage zones go to the
System Configuration screen.
2. Enter a readily identifiable name for
the zone (ie Mast, Deck House or
Stack).
3. Moving to the right, enter the relative
of the starting point of this blockage
zone (the more counter-clockwise
bearing).
4. Then enter the relative bearing of the
stop point of this blockage zone (the
more clockwise of the two bearings).
