I had to take a closer look at your question and at the standard.
You don't have to worry about the bench, chamber, cabling and LISN's
(see Figure 2) when you bring a transmitter into the chamber for CE106.
The exemption also means you don't have to take a transmitter out of an
armored vehicle,ship or aircraft if you can carry the measurement
receiver to the transmitter. Conducted is MUCH easier than radiated;
note the far field measurement distance requirements at 5.18.3.4a.
I don't see how many transmitters *with the "intended antenna"* could
even fit inside a chamber let alone at the measurement distance needed,
and that alone makes Figure 2 impossible.
(Doing a few calculations, the radiated option seems best invoked
in-situ, and then only if one absolutely must -- and is herded there at
gunpoint.)

So I am apparently missing something. How could RE103 emissions
measured in either a anechoic chamber or OATS be independent of the
test setup configuration? What is really meant by "the basic test
setup described in the main body of this standard."?
And yes, I've checked 461E, which reads essentially the same.
