Rf Interference - KVH Industries TracPhone FB250 Installation Manual

Appendix C: Grounding and RF protection
C.10 RF interference
Interference induced from nearby RF transmitters might cause system failures
and in extreme cases permanent damage to the TracPhone equipment. If
problems with interference from HF transmitters are encountered, it is
advisable to 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.
C.10.1 Recommendations
1-5 pcs. hinged clamp cores (e.g. the RFC or SFC series from Kitagawa)
mounted on the antenna cable near the antenna.
