CAUTION: BEFORE STARTING TO ASSEMBLE THE ANTENNA END CONNECTOR, USE COOLING AND LUBRICATION TO MINIMIZE THE LIKELIHOOD OF UNSEASTING ITS GAS BARRIER O-RING. Choose an appropriate time of day or use refrigeration to keep the connector temperature at 24° C (75° F) maximum at the time of installation, and use a thin coating of supplied silicone grease (#12225) to lubricate the inner surface of the connector outer conductor. The cooler temperature plus the lubrication will allow the inner assembly to slide easily within the outer conductor.
1. Remove the protective covering from the ANT end of the final cable section. Align the threaded stud on the connector inner conductor assembly with the final cable section inner conductor, taking care to support the connector during assembly. Position the inner assembly to expose the integrated driver ring and thread the stud into the stub of the final section inner conductor. Turn the assembly by hand until the contact surfaces are snug.
CAUTION: TO PREVENT MISENGAGEMENT, THE INNER CONDUCTORS SHOULD BE ALIGNED WELL. The inner conductor assembly should turn freely during initial tightening.
2. Attach the inner conductor tool (#220335) to the final section inner conductor, with the edge of the tool about 0.25 inch (6 mm) from the edge of the integrated driver ring.
CAUTION: NEVER ATTACH THIS TOOL MORE THAN 0.5 INCH (12 MM) FROM THE DRIVER RING EDGE. This can damage the inner conductor.
3. Remove the spanner wrench attachment from the driver-ring torque wrench (#220047) and replace it with the (ANT) spanner wrench (#220303). Tighten the connection to a torque between 250 and 275 ft-lb. The inner conductor tool is used to hold the inner conductor of the cable section stationary and the torque wrench is used to turn the inner conductor assembly. Tightening is easier if the arm of the inner conductor tool is kept out of the way of the torque wrench arm.
CAUTION: USE THESE WRENCHES ONLY. They are designed to prevent damage to the inner conductor and connector assembly. Also, DO NOT ROTATE THE INNER CONDUCTOR TOOL during tightening. For a low-level installation, a tool rest is available to hold the arm of the inner conductor tool fixed.
4. This is a high contact pressure connection. After tightening, brush completely around the connection (between the integrated driver ring and inner conductor) to remove any small fillings that occur from the wiping action of the contacting surfaces. Use a soft horsehair brush or equivalent.
5. Butt one end of the pretension gauge (#220043) against the strain insulator of the final section and rotate the strain insulator until the edge of the inner conductor assembly is aligned with the opposite end of the gauge. This sets the proper strain on the inner conductor of the final section.
6. Check the installation of the flange O-rings and reinsert them into their corresponding grooves as required.
