Flamingo+ FM - Broadcast FM Bandstop Filter v2 (FM Notch Filter) for Software Defined Radio (RTL-SDR) Applications. Blocks Problematic 88-108MHz Frequencies from Your SMA-Connected Radio
Flamingo+ FM (Flamingo FM v2) is a high attenuation bandstop filter designed to stop very strong broadcast FM transmissions from causing overload and other issues with your radio or SDR
The attenuation level of this filter is much higher than Flamingo FM v1 (>60dB typical avg. & >70dB typical max attenuation). We recommend this filter for urban environments and other locations with high-wattage FM transmitters nearby. For other locations, Flamingo FM v1 is a better option
Flamingo+ FM has a higher attenuation than other similar commercial filters, while also have a lower insertion losses outside of the stop band (<0.25dB avg.) and less of an effect on the adjacent VHF airband of 108MHz-137MHz (8dB avg. attenuation vs 16dB avg. of similar filters)
