An antenna can be specified by the index of the antenna or a regular expression. A full antenna name consists of three hyphen ('-') separated fields. The first field is the antenna name, the second is the side band name and the third is the polarization name. Each of the three fields can be a regular expression. All missing fields after the last specified field are replaced by "wild card" regular expressions.
E.g., a fully qualified name for C11, upper side band, 175-MHz polarization channel (nominally the LL polarization) can be expressed as:
C11-USB-175
All central square antennas, with upper side band and 130-MHz (nominally the RR polarization) polarization channel can be expressed as:
C.+-USB-130
(Here '.' matches one instance of any character and the '+' operator operates on '.' zero-or-more number of times. Hence ".+" is equivalent to the '*' wild card character. This is the POSIX regular expression syntax).
All central square antennas with upper sideband and either polarization channel can be expressed as:
C.+-USB-.+
or simply
C.+-USB
Finally, all central square antennas without any selection on the side band and polarization channel can be expressed as:
C.+-.+-.+
or simply
C.+
All above examples, but with only arm antennas can be expressed by replacing ``C.+'' in the above examples by ``[EWS].+".
