Replacing the Calibrator Semi-Rigid/Split Ferrite
Instructions Visual
• Separate the two halves of the ferrite
(Figure 6-23)
• Position the ferrite such that it’s furthest
edge is 120 mm (4 ¾”) from the bend of the
semi-rigid (Figure 6-24)
• Hold the ferrite in place by applying a
coating of silicone or silicone-rubber
compound (e. g. RTV) along that 20 mm (¾”)
section of the semi-rigid
• Join both halves of the ferrite, keeping the
mating surfaces free of the silicone
compound if possible
