RF48H is a converter discovered by Stephen Silver in October 1997, as an alternate completion of Paul Callahan's Herschel receiver. As of the end of 2017 this converter has four known variants. The original version consists of a single transparent loaf. In the pattern shown, a ghost Herschel marks the output location. To avoid hitting the loaf predecessor, the output Herschel's FNG must be suppressed by connecting the converter to a dependent conduit, or by using an eater 5 or sidesnagger.
The loaf can be shifted one cell up and flipped to produce a different conduit, RF28B, with an improved recovery time. The extra block of the B-heptomino is not cleaned up in that case, unless an elementary conduit with a B-heptomino input is added.
