  • Notes
  • The Radiospares Anti-Parasitic Beads are used for the suppression of parasitic oscillations in HF RF amplifiers, which can render the tuning characteristics of the amplifier erratic, reduce the efficiency at the operating frequency and possibly cause interference by unwanted radiation. The ferrite beads can be slipped on to the wiring to damp out any tendency to oscillate at VHF. Several beads can be used close together if required.
