Whenever you put any device is series, expect to lose something. For
example with a series diode expect to lose about 0.5volt.

For this reason many radio manufacturers use a back-biased diode across the
supply and a series fuse. In this way no current passes through the diode
unless you cross-polarity the radio, in case it will be a short to blow the
fuse.
