Cmc-330-5k
CMC-330-5K Common Mode Choke / Noise Suppressor / RF Isolator The best Common Mode Choke for 3-30MHz on the market. There is no similar product available matching the performance of CMC-330-5K. Perfect to cure RFI/EMI problems. It is a cure for noisy locations, reducing the noise floor of your receiver by several S-units instantly. If you have unbalanced antennas such as OCF dipole or your antennas close to your home, adding one CMC-330-5K 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. Most important, the value of CMC-330-5K Common Mode Choking Impedance and its Resistive (Rs) part is always higher than the Reactive part (Xs) over the working bandwidth.
This parameter, Rs>Xs ensures that our CMC will NOT increase common mode currents as could with inferior coaxial cable chokes. Only chokes with Resistive (Rs>Xs) CMI- Common Mode Impedance stops and dissipate unwanted RF or noise coming to your equipment for sure. CMC-330-5K Features: Two large 2.4? (61mm) custom Ferrite cores for maximum Choking Impedance and bandwidth. SO-239 PTFE (Teflon) Connectors which produce no impedance bump but the continuity of coaxial cable where the choke is inserted, help minimize leakage of RF in multi/contest station setups. PTFE (Teflon) insulated coaxial cable is used, reduces RF leakage, and can handle a lot more than legal power (1500W) in the USA. Rated at 5kW ICAS Enclosure with mounting flanges for easy installation inside or outside the station setup. It has been tested for UV (Ultra Violet) exposure for the past eight years with no impact on the material.
