Figure: GPS Antenna mounted on a pole with a free view of the sky. The optional surge protector keeps high
voltage strikes through the antenna cable away from the receiver.
Mounting material (plastic pole and holders, clamps for wall or pole mounting) is shipped with all Mein-
berg GPS antennae for easy installation. A standard RG58 antenna cable of 20 meters length is included by
default. If a different cable length is required then this can be ordered accordingly.
Surge protectors should be installed indoors, directly where the antenna cable comes in. The optionally
delivered protection kit is not for outdoor usage. The ground lead should be kept as short as possible and has
to be connected to building’s ground rod.
Up to four GPS receivers can be fed by a single antenna/down-converter unit by using an antenna splitter
which can optionally be cascaded. The total length of an antenna cable from the antenna to each receiver must
not exceed the specified maximum length according to the cable type. The position of the splitter in the antenna
line does not matter.
