• clear view towards equator (if clear view of 8 not possible) or • clear view between 55th north and 55th south parallels (satellite orbits). Information: Problems may arise if all of these views are obstructed, as four satellites must be located to calculate a new position.

- Page 22 Type-N (Male) If installed in a waterproof housing, the MBG S- Type-N (Female) PRO can be installed outdoors. However, Meinberg recommends installing the surge protector indoors—as closely to the entrance point of the antenna cable as possible—in order to minimize the risk of surge dam- age (such as that caused by lightning strike).
