Watts maximum
0.7 Amperes @ 27.50 Vdc
1.6 Amperes @ 13.75 Vdc
Standby current:
0.400 A @ 28 Vdc
0.758 A @ 14 Vdc
Lighting current:
55 +/- 17 mA @ 28 Vdc
110 +/- 34 mA @ 14 Vdc
The RF input level required to produce 90% replies will
not vary by more than 1 dB between modes and will at
no time exceed a level of -69 dBm for standard
ATCRBS interrogations in the frequency range
between 1029.8 and 1030.2 MHz.
A standard ATCRBS interrogation signal below 1005
MHz and above 1055 MHz will be at least 60 dB
stronger than that required to produce the same reply
efficiency at 1030 MHz.
