Microsemi NTP Server Antenna Kits


The SyncServer GNSS Antenna system allows the device to quickly and securely retrieve Stratum-1 time reference from multiple Global Navigation Satellite Systems, including GPS, GLONASS, Galileo and more. With the capability to reach antenna lengths of up 1500 feet, Syncworks is prepared to offer a solution to service most all deployments and locations.

SKU: 990-15202-000 Category:


The SyncServer GNSS Antenna outdoor antennas and associated cable lengths are often one of the biggest variables to consider when implementing a new system. There are pre-configured Antenna kits available in popular distances if you are confident in your requirement. Otherwise, the Syncworks sales team is happy to help discuss, configure and quote your most appropriate antenna configuration. Pre-configured kits include coax cable, antenna, and related mounting accessories. These kits vary by total cable length and based on whether a lightning arrestor is required or not.

Important: The antenna kit (part number 093-15202-001) includes a short SyncServer adapter cable with BNC(m)-N(f) connectors. All primary antenna cables use N(m) connectors on either end. A single cable must be used between the adapter cable and the next accessory (lightning arrestor, in-line amplifier, or antenna). Lightning arrestors include a 25 ft. cable to connect to the next accessory (inline amplifier or antenna).

Lightning Arrestor Info & Specs

Lightning does not have to strike the antenna to significantly damage the antenna or the GNSS receiver. Damage is often due to the effects of a lightning strike on a nearby structure, not a direct strike on the antenna itself. Since lightning strikes may induce damaging voltages in the antenna system when striking nearby objects, attempt to locate the antenna away from lightning rods, towers, and other structures that attract lightning. Also, locate the GNSS antenna lower than any nearby structures that are likely to attract a strike.
