HF antenna Line Isolator 1-54 MHz/ Rated @3kW / stops RFI / RF choke
"The common-mode filter or choke may be one of the best-kept secrets". American Radio Relay League Antenna Handbook. If you use End Fed antenna aka 9:1 UNUN with a piece of wire, OCF dipole antenna or have any RFI problem, use the best tool to cure it. Great for CB and HF mobile operation. Do not fall for those coiled coax chokes which can make the problem worse in some cases.There is no shortcut when it comes to curing RFI/EMI problems after all Ferrite materials are invented for that purpose. Ferrite turns the RF energy into heat, coiled coax does not! CMC-154-3K Common Mode Choke / Noise Suppressor / Line Isolator / RFI Suppressor Designed by Danny Horvat, E73M -former Cushcraft antenna designer. CMC-154-3K Common Mode Choke / Noise Suppressor / RF Isolator. The one and only true Common Mode Filter Choke for 1-54 MHz on the market.
It is only product with over 7000 Ohms of CMI on 50MHz while maintaining a Resistive part of CMI for more then50MHz of the frequency spectrum, actually, it has same values all the way up to 85MHz. Perfect to cure RFI/EMI problems. Common-mode attenuation is up to 39dB max.
(measured in 50 Ohms systems). It is a cure for noisy locations, reduce the noise floor of your receiver by several S-units instantly. If you have unbalanced antenna such as OCF dipole or your antennas close to your home, adding one CMC-154-3K will greatly reduce RF Interference problems on your equipment and 120/220V wiring inside your home. We do not claim "one size fits all" but actually we design, measure and make such products. Unlike other companies, we do not claim unrealistic impedance values or frequency coverage.
