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. Designed and manufactured by Nooelec in North America, with a full 2-year product warranty.

A high-quality, high-performance broadcast AM bandstop filter designed for software defined radio SDR applications. Includes free male SMA-male SMA barrel connector Designed and manufactured by NooElec in North America. Impeccable quality and full 2-year warranty. Broadcast AM stations can be particularly problematic due to the high-powered transmitters used for broadcasting in some areas. These signals can overload the front end of an SDR, causing imaging and a number of other issues. As such, Flamingo AM makes a great companion to our Ham It Up series of HF upconverters available separately on Amazon. Flamingo AM was designed to provide approximately 40dB attenuation for broadcast AM frequencies, while ensuring that adjacent bands are minimally affected. The -3dB rolloff of the filter is 350kHz and 1900kHz. The minuscule out-of-band insertion losses means the filter can stay in place for most any application--though we do recommend removing Flamingo AM from the signal chain when not receiving HF frequencies. Flamingo AM is a proper bandstop filter, so you are able to pass-through DC bias-tee power when required. DC current handling is 250mA min, and the maximum recommended signal level is 18dBm 5Vp-p, so there is no issue using the filter for higher-power applications. The filter is fully EMI shielded, installed in a custom anodized aluminum enclosure for further protection and isolation. The front end is protected by an RF-rated ESD diode, which provides protection not just for your filter, but also the radio or SDR behind it.
