5. The SR Series NTP Server has an integrated GPS receiver An optional external antenna provides synchronisation with the global positioning system GPS solutions can be utilised anywhere in the world The optional GPS antenna is a high gain jam resistant pole mounting GPS antenna For correct operation the GPS antenna needs to have an un obscured view of the sky As a rule of thumb the better the view of the sky the more chance of a good consistent signal lock Ideally the antenna should be roof mounted with a 360 degree view of the sky However satisfactory operation can often be achieved by sitting the antenna on the side of a building or on a widow sill 8 1 Typical Maximum GPS Cable Length TWS3978 GPS Antenna Cable Type Max Cable Distance Max Cable Distance with Single GPS Amplifier RG58 30m LMR195 50m 100m LMR200 60m 110m LMR240 80m 140m LMR400 150m 260m LMR600 230m 400m 8 2 SRxxxx 10 and SCxxxx 10 High Sensitivity GPS Receiver Later SR and SC series NTP servers with model postfix 10 and later are fitted with a high sensitivity GPS receiver with over determined clock The high sensitivity mode often allows the GPS antenna to be located indoors or in a window considerably reducing installation costs and eliminating the need for surge suppression The over determined clock mode allows the receiver to operate from a single satellite in view which allows the receiver to obtain a signal
