approximately 42 BTU per hour of heat. The G3L-929-135 amplifier is designed to operate within the
extended low temperature and high temperature environments defined in Table 1-1.
Table 2-1 describes the heat load (at 120 Watts typical) for a 3-sector (70%), 2-sector (80%), omni (90%),
and typical (100%) site. Perform a site survey to determine actual air conditioning needs.
