7 GNSS Antenna Installation 7.1 Installation of the Multi-GNSS Antenna Danger! Do not mount the antenna without an effective fall arrester! Danger of death from falling! • Ensure that all necessary safety measures are taken when installing an antenna! • In particular, never work without an effective fall arrester! Danger! Do not work on the antenna system during thunderstorms! Danger of death from electric shock! - Page 31 Case Example 4: If the cable leading from the point of entry into the building to the Meinberg system is laid together with other cables (for example in a cable duct alongside high-voltage cables), transient voltages may "leak" into the antenna cable, causing damage to your system.
- Page 32 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).
