Positioning the connector
See Figure 3-7. Maneuver the clamp over the RF connector and onto the test
port connector.
1. Hold the test cable with one hand. Use the other hand to press the clamp
gently and steadily, as you wiggle it into position straight over the RF
connector and onto the test port connector nut.
NOTE Be sure to loosen the clamp when you are slipping it over the connector.
2. Fit the internal flats in the clamp over the flats on the test port connector
nut.
3. Avoid rotating the clamp as you position it so the RF connection remains
tight (remember it loosens easily).
