GPS Low Noise In-Line Amplifier (LNA), SMA Connection
$99.99
TimeMachines® GPS In-Line Low Noise Amplifier (LNA). By using the TimeMachines® LNA, longer cable runs can be supported. In addition, more cable splits can be accommodated with our passive splitters. The standard unit includes SMA connectors and is a direct mate to the TimeMachines® splitters. A TimeMachines® TM1000/2000/2500 can supply power to up to one splitter and the antenna utilizing the LNA’s pass through power functionality.

Description
The TimeMachines® GPS Low Noise In-Line Amplifier (LNA) product was created to both extend the length of cable that can be used between a time server and the outdoor antenna, as well as allow for a greater number of signal splits to occur downstream of the outdoor antenna.
The Low Noise In-Line Amplifier (LNA) was designed specifically for GPS signal amplification in timing environments by TimeMachines®. These basic indoor amplifiers are made with a simple PCB design and 3D printed enclosure to maintain the TimeMachines® commitment to price and performance.
Power Requirements: The important thing to note about the power requirement is that currently shipping TimeMachines® time servers (TM1000A, TM2000B, TM2500C) can supply power to run ONE LNA plus the antenna. If more than a single LNA is put into series in the line, then a power source separate from the time server itself is required. TimeMachines® 2 and 4 port splitters with power injection can be used for this (SKUs: 760-602-PWR and 760 604-PWR). Even if the splitting function isn’t required, the ability to inject 9V onto the center conductor of the antenna cable will enable multiple LNA devices to be placed into the cable running to the antenna. The LNA is also capable of passing power through to the next device which could be another LNA, or the antenna itself. Installation: The next pages cover the common installation methods. It is critical that the input/output orientation be followed. Power status can be confirmed by looking through the hole on the side of the unit for the LED. Connections: RF In Port: should point toward the Antenna. It is also important that at least 25ft of cable be between the antenna and the LNA. Less that will over-saturate the input to the LNA causing degraded performance. RF Out Port: should point toward the time servers A simple 5/16 inch plastic wrench is included to help with the tightening of the SMA nuts.
