4. BACK PANEL INPUTS AND OUTPUTS

ANT: Antenna Connector (SMA Connector)

ANT is the GNSS antenna input port. The antenna port provides an interface for an
external active antenna via low-loss coaxial cable: 50 Ω impedance. 5 V DC @ 50 mA max
is supplied to power an active antenna. The total combined gain of the antenna system
(antenna plus cable and connectors) should fall in the range of 10 to 35 dB, the optimum
being 22 dB.
If the Fiber-Slave option is ordered, the antenna is replaced by a fiber input port.
Care should be taken to ensure that the connector is not cross-threaded when
attaching the antenna lead-in cable. The connector should be tightened firmly by
hand only. Do NOT over-tighten!

Antenna Cable Considerations:

Note: The following figures are based on an average GNSS signal strength of -130dBm at sea level.
CNT-240
CNT-400
A lightning protection device should be inserted into the antenna lead. A suitable device complete
with additional cable connectors, a connector crimping tool and mounting hardware is available as an
option (FACTORY HARDWARE OPTIONS). Introduction of the lightning protector does not degrade
the performance of the antenna system.
