156 -163 MHz marine band is higher in frequency than 118 - 136 MHz
aviation band, but not by much. A quarter wavelength in the middle of
the aviation band is about 23 inches and a quarter wave in the middle
of the marine band is around 18 inches, but your marine handheld
shouldn't care about a little mismatch. Just verify that the cable is
good, hook it up and try it.
