C language of NEC2, the FORTRAN Numerical Electromagnetics Code commonly used
for antenna simulation and analysis.  It can be used to define the geometry of
an antenna, and then plot the radiation pattern or frequency-related data like
gain and standing wave ratio.")

       "@code{rfcat} is a program to control some radio dongles operating in
ISM bands.

Supported dongles:
@itemize
@item YARD Stick One
@item cc1111emk
@item chronos watch dongle
@item imme (limited support)
@end itemize

To install the rfcat udev rules, you must extend @code{udev-service-type} with
this package.  E.g.: @code{(udev-rules-service 'rfcat rfcat)}")
