[time-freq] Efratom GPS Antenna

I have a new Efratom GPS timing antenna that I hope to use for a
GPS-disciplined frequency standard.  The antenna itself is a black cone
about the same shape and size as a disposable 10 ounce foam coffee cup.  The
base of the antenna has a sticker that reads:  EFRATOM PN 012003-004 GPS
ANTENNA.  The electrical connection is through a female TNC jack.  The
antenna is mounted with four screws to the top of an aluminum fixture that
has a female N connector on its bottom end.  The antenna and fixture, along
with an Andrew cold-shrink kit and some hardware, are packaged in a foam
tray that has the part number 104545-001.

In order to use this antenna without either damaging it or operating it
inefficiently, I need to know what voltage it is designed to accept.  My
searches on the Internet have been fruitless.  Can anyone on this list share
some details about its specs?
