The pqact.conf examples can be found from either the tutorial or
the GEMPAK 5.6 configuration for products:
http://www.unidata.ucar.edu/packages/gempak/GEMPAK5.6/configuration.html

Specifically, for NEXRAD data:
http://www.unidata.ucar.edu/packages/gempak/tutorial/pqact/images.tbl

Gives:
##########################################################################
# NIDS Data from NOAAPORT
##########################################################################
NEXRAD  ^SDUS5. .... ([0-3][0-9])([0-2][0-9])([0-6][0-9]).*/p(...)(...)
        FILE    -close  data/gempak/nexrad/NIDS/\5/\4/\4_(\1:yyyy)(\1:mm)\1_\2\3




If you wanted to store data from SHV, POE, JAN, and LIX for example,
you would match those ID's in the PIL portion of the pattern, such as:
NEXRAD  ^SDUS5. .... 
([0-3][0-9])([0-2][0-9])([0-6][0-9]).*/p(...)(SHV|POE|JAN|LIX)


The pattern will store the data in files under 
~ldm/data/gempak/nexrad/NIDS/xxx/NNN/NNN_YYYYMMDD_HHNN
where xxx is the 3 letter site identifier and NNN is the product
identifier (such as N0R, N0R, NTP, N0S, NCR, etc).

Your Gemenviron file should define RAD as the data directory
~ldm/data/gempak/nexrad following the above pattern action.

The $GEMTBL/config/datatype.tbl file that NMAP/NMAP2 read to find the data
is set to look at $RAD using the NNN_YYYYMMDD_HHNN file naming as provided
in the pqact.conf examples.
