And for years we have referred to them as "daughter boards".

In this case the term “shield” has been overloaded and has nothing to do with coaxial
cable. It is simply the term for an Arduino add-on board. Similarly, Beaglebone’s have capes,
and others name their boards with unique names.

I have a plan to use an audio shield (velleman KA02) using ISD1700 for Arduino.
Builtin switches on the shield will not be used, and it will be controlled via
USB serial so that logging software can handle.
A cable shield must NEVER be connected to anything but the shielding enclosure
at the point of entry. Putting that another way, a cable shield must ALWAYS be
connected directly to the shielding enclosure at both ends. Anything else is a
source of hum, buzz, and RFI.
Yes, I know that nearly all ham rigs fail to do this, but the manufacturers are WRONG.
For engineering analysis of this, see my tutorials on "The Pin One Problem" on
my website, also the AES Papers on my website, and the tutorial appendix to AES48, which
can be downloaded from the AES Standards website (but not free).
