RF interference

Interference induced from nearby high-power RF transmitters might cause system failures
and in extreme cases permanent damage to the FV-110GX 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.
