Tube Feed Line Chokes

RFI Solution Kits

Palomar Engineers provides a variety of Radio Frequency Interference (RFI) and Electro-Magnetic Interference (EMI) solutions from 100 KHz to 1000 MHz.

We have many RFI solution kits targeting common RFI problems encountered by consumers, broadcast professionals, radio operators, industrial plant managers, marine/ship operators, solar power contractors, etc. For custom individual RFI problems we offer individual ferrite RFI suppression components in bead, snap on and ring topology to fit various wire/cable configurations for AC/DC power cables, coaxial feed line, and device interconnect cables.

Different ferrite mixes suppress different frequency ranges. To select a mix for your interfering frequency see: Choosing a Ferrite Mix

TUBE feed line chokes/Line Isolators are used to suppress common mode current carried on the outside of the  coax braid which is often responsible for receiver noise and RFI in the receiver/transmitter. These chokes are very useful for suppressing RFI common mode current at the antenna feed point, at 1/4 wavelength intervals along the coax feed line and also at the entrance to the radio station.  They are available with various input and output connectors so as to conveniently connect to standard output connectors already installed on your feed line.

Palomar Engineers TUBE feed line chokes are designed to have 2-5 times more choking impedance over a broader frequency range than competitor units in similar packaging.  Each choke has the choking impedance and effective frequency range on the product label so you can choose the product best suited for your application.
