The PocketWizard AC5 RF Softshield is the same RF Shield that is now packaged with the PocketWizard FlexTT5.
This two-piece shield consists of a separate mounting foot and "sock" that slips over Canon 430EX, 580EX and 580EXII flash units and isolates them from the remote FlexTT5 antenna and circuitry which greatly improves flash operation.
The AC5 is not necessary for a camera-mounted FlexTT5 used as transmitter.

The Softshield works. I went from about a 20 foot range to well over 100 feet. It makes the Pocket Wizards work out to very long distances. If you are experiencing radio ranges that are very limited, this will solve that problem.
