The modem is already certified. And the antenna is also cerified. I don't see any use in doing a quite expensive cert for both again (btw 5000$ will definitely not suffice, it's rather 4 times as much, maybe more, incl. all procedures and action to get accomplished). What you're asking is like asking for a CE cert for the particular combination of an incandescent bulb (already type approved CE) in a particular desk lamp (also already CE approved), just because we screwed that new bulb into the lamp. /j
