Removing bytes from the beginning of each frame?

["Barta Frank-QKBF84" <frank.barta () motorola com>]

Hello,
 
I've been working on finding a method to remove RadioTap headers from an
802.11 capture. I've found that I can change the file encapsulation in
editcap from ieee-802-11-radio to regular ieee-802-11, however because
the packet bytes for the radiotap header still exists this results in
mostly garbage data.
 
I know that the radiotap header is going to be the first 20 bytes of
every frame in the given capture I am working with. Editcap appears to
only have a method for chopping data off of the packet at the end, and
not at the beginning. Does anyone know of or have a tool that will allow
me to remove the first 20 bytes from every frame in a capture?
 
Regards,
