Physical Protection When routing the antenna cable protect it from physical damage which may result from closing doors falling objects foot traffic etc Also when routing around corners allow for sufficient bend radius to prevent kinks Extra length should be allowed at both ends of the cable to prevent tension on the connectors which could cause damage or failure Extra length is useful as a service loop in the event that a connector needs replacement Do not stretch the cable mid air over any appreciable distance without support Cable degra dation or failure could result Always leave a drip loop wherever the cable enters a structure to prevent water from entering the structure via the cable jacket The maximum temperature rating for the type of cable provided with the clock is 75 C 167 F Exercise care when routing the cable near sources of heat to avoid cable damage 4 4 Technical Details on GPS Antennas and Cables 21 Adjacent Signals Although the standard RG 6 style cable is triple shielded and has excellent shielding properties be cautious when routing near high power RF sources or alongside cables carrying high power RF such as transmitter cables In these applications consider using RG 11 style cable P N WC0004900 Its quad shielded design provides even more isolation Antenna Power The RF preamplifier within the antenna requires 5 VDC at 15 mA nominal for operation A power supply within the clock generates thi
