B.7 RF interference
Interference induced from nearby high-power RF transmitters might
cause system failures and in extreme cases permanent damage to the
SAILOR 100 GX equipment.
If there are problems with interference from HF transmitters, do as
follows:
1. Mount ferrite clamps on the coax cable in order to provide
suppression of induced RF. The ferrites will have no effect on the
differential-mode signals but increases the impedance in relation to
common-mode RFI.
2. Use 1-5 pcs. hinged clamp cores (e.g. the RFC or SFC series from
Kitagawa) mounted on the ADU cable near the ADU.
