Figure 2-38.AN/SRA-12 antenna filter patch panel with receiver antenna patch panel.
Figure 2-38 shows a receiver antenna filter patch
panel, AN/SRA-12, with a receiver patch panel. The
AN/SRA-12 provides seven radio-frequency channels
in the 14-kHz to 32-MHz range. Any or all of these
channels can be used independently of any other
channel, or they can operate simultaneously.
On the receiver patch panel, a receiver is hardwired
to each jack. With the use of patchcords, you can
connect a receiver, tuned to a particular frequency, to the
antenna by connecting the receiver to the proper jack on
the AN/SRA-12. Figure 2-38 shows how the filter
assembly is used in combination with other units to pass
an RF signal from an antenna to one or more receivers.
When patching, YOU MUST ALWAYS
INSERT THE END OF THE ANTENNA
PATCH CORD TO THE RECEIVER
JACK FIRST. THEN, YOU INSERT THE
OTHER END OF THE PATCH CORD
INTO THE LOWEST USABLE AN/SRA-
12 JACK. TO UNPATCH, ALWAYS
REMOVE THE PATCH CORD FROM
THE RECEIVER JACK, THEN THE
OTHER END FROM THE FREQUENCY
FILTER JACK. An easy way to remember
this is always work the patching from the top
Transmitting antenna distribution systems perform
the same functions as receiving distribution systems.
