The Diamond Line 2 amplifier modules vary in highest forward
frequency, ALSC pilot frequency, and station output tilt.
Diamond Line 2 amplifier models vary in three ways: highest
forward frequency, automatic level and slope control (ALSC)
pilot frequency, and station output tilt. For example, model
6-G3A298/37–42/54–433–100 (variable elements
underlined) specifies the following:
•
a highest forward frequency of 870 MHz,
•
a 433.25 MHz ALSC pilot frequency, and
•
10 dB station output tilt over the forward bandwidth.

ALSC Pilot Frequency— Station Output Tilt
for example (over the forward
427 = 427.25 MHz bandwidth)—
433 = 433.25 MHz 080 = 8.0 dB
499 = 499.25 MHz 125 = 12.5 dB
110 = 11.0 dB
100 = 10.0 dB
147 = 14.7 dB
