Ferrite Interference Choke ; Two piece snap-together assembly wraps around coax. Removes RF from outside of cable. It is possible to make 2 or 3 turns of smaller coax. Several chokes will isolate end of coax for balanced feed (balun). Useful on mic leads & computer cables. Excellent for reducing RF on a mobile linear's +12V lead. New low pricing. Product Description. RF Choke 470uH. Q 60min. 126 mA DC. Small RF Choke. Epoxy coating makes them nearly impervious to mosture and humidity. Ferrite Chokes in the Antenna System. A transmitting choke creates a high impedance in the path of common-mode (CM) RF current that a feed line would otherwise pick up from a transmitted signal. That interaction is called coupling, and blocking the current is called decoupling. Coupling between a feed line and an antenna can distort the. The Sirio Gain-Master is a high tech fibreglass base station antenna for CB and 10m amateur band. Completely designed by electromagnetic simulation to achieve the maximum gain and optimize the radiation pattern and bandwidth. Engineered with the most advanced available technologies it is completly manufactured in Italy with high quality materials. The RF interference is originating in the. ignition system - possibly a bad spark plug wire. or distributor cap. This is generally a "ticking". sound. If you can hear the separate ticks at. an idle, it is probably a wire or plug, otherwise. it is in the coil, coil wire, or cap. RF noise is.
