- Page 2 GNSS Antenna and Receiver Installation Guidelines Falcon /G models (µFalcon-MX/G, Falcon-MX/G, µFalcon-ST8/G, Falcon-MTS and Falcon-RX/G) include an integrated Global Navigation Satellite System (GNSS) receiver. It is a multi-constellation (GPS, GLONASS, Galileo, Beidou) receiver designed to provide high precision and stable synchronization in Telecom and Enterprise environments.

Page 3: General Considerations
• Use professional and adequate accessories for installation. Such may be ordered (optionally) from Fibrolan. • Position the GNSS antenna at a minimum of 1.5m / 5 ft distance from any metallic object and a minimum of 1m / 3 ft distance from any other GNSS antenna •... -

(perhaps none at times) of satellites to track. Figure-2: Examples of antenna installation location In cases where good sky dome exposure cannot be secured, consult Fibrolan for alternatives based of extended holdover and other unique mechanisms available on certain models. Such, will maintain synchronization for a given period even at the absence of adequate satellite signals. -

G P S / G N S S A n t e n n a I n s t a l l a t i o n G u i d e l i n e s 2 Antenna and transmission system selection It is recommended to obtain the antenna, cable and other accessories from Fibrolan along with the timing device. This will ensure full support and higher performance of the solution. -

If more than a single receiver is connected to the antenna a powered/amplified splitter is installed. Figure-5: Multiple receiver installation with splitter 2.2.1 Cables Fibrolan recommends using 50Ω or 75Ω coax cable for connecting the GNSS antenna to the Falcon GNSS receiver port. •... - Page 7 (typically 0.1dB). 2.2.3 In-Line Amplifier In case the total gain at the Falcon GNSS input drops below 15dB an in-line amplifier is required. For example, Fibrolan’s GNSS antenna model GPANT-4's gain is 28dB, which can be translated to a maximum of 13dB attenuation for the entire transmission system (indoor+ outdoor) without amplification.
