Blade E-Field - Honeywell SPZ-8000 Maintenance Manual

11. D.
AT-803 Antenna Coupler Unit (ACU) -
Blade E-Field (See Figure 11-5 and
Table 11-6.)
The AT-803
ACU receives Omega/VLF signals and
converts them for
processing by the OZ-800 RPU.
The AT-803 contains amplifier stages that
amplify the received signals sufficiently to allow the signals to be
cable-transmitted to the OZ-800 RPU without significant signal-to-noise
degradation.
The AT-803
ACU
is
used when a suitable location
for the
AT-800 or AT-801 H-Field
ACU
cannot be located by an aircraft skin map
because of excessive RFI aircraft noise.
