b. Weights and Dimensions of Antenna Assembly.
(1) Ready for Movement (Packed). Al 1 the components of the AS-3577/GRC
are packed in one carrying case (see illustration on page 4-27), which is equipped
with four carrying handles. The carrying case is 4.125 feet long, 1.875 feet wide,
and 1.5 feet deep (1.258 by 0.572 by 0.457 meters, respecti vely). It weighs 260 lbs
(.108 kg) .

1-13. Configuration Differences. There is a difference in the configuration of
operable transmitting and receiving antenna assemblies. Only transmitting antenna
assemblies require the caution (rf radiation hazard) plates attached to the safety
area rope.
