🌀 Product Overview
The Diamond CMF2000 is a high-performance common mode filter designed to suppress unwanted radio frequency interference (RFI), including TVI (Television Interference) caused by common mode currents in the HF and 50MHz bands.
With up to -50dB attenuation, this filter ensures cleaner signal transmission and more stable operation, particularly in environments where interference is more likely—such as in the lower HF bands.
⚡ Key Features
Reduces common mode radiation and interference across the 1–54MHz range.
Compatible with digital TV systems.
Handles high power up to 2kW SSB, suitable for robust amateur radio operations.
Low insertion loss (≤ 0.2dB) preserves signal integrity.
