Recommendations
Access to the immediate vicinity of the antenna (reflector and feed) must be restricted to
trained customers and certified contracted/service personnel. No member of personnel
should interpose any of their body parts between the feed and the reflector while the
terminal is transmitting. At full output power, this region is dangerous in cases of
exposure of more than about 14.6 seconds.
At full output power, the near-field output of the auto acquire terminals exceeds the
allowable levels for
continuous
exposure in an
uncontrolled
area. This near field is a
cylindrical region which encloses the reflector and points toward the satellite. Because
many sites accommodating the auto acquire terminals are accessible to non-operational
personnel, these sites should be considered as uncontrolled and the recommended
precautions taken accordingly.
The primary precaution should consist in restricting access to the immediate area in
front of the reflector to short durations, which, according to worst-case assumptions,
means that access should be limited to less than 10 minutes within any 30-minute interval.
If
limited-duration
access cannot be insured, then
no
access should be allowed within the
distances specified in Table 2-1 below. (Table 2-1 assumes a member of personnel
standing 6ft tall at ground level. The horizontal distance must be scaled upward
accordingly if the members of personnel are at a level higher than 6 ft.).
