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

Flamingo FM - Broadcast FM Bandstop Filter (FM Notch Filter) for Software Defined Radio (SDR) Applications

A high-quality, high-performance bandstop filter designed for software defined radio (SDR) applications. Includes free male SMA-male SMA barrel connector!
Flamingo FM was designed to provide approximately 40dB attenuation for broadcast FM frequencies, while ensuring that adjacent bands are minimally affected. The -3dB rolloff of the filter is 80MHz and 115MHz, which means the VHF airband (108-137MHz) is minimally affected. The minuscule out-of-band insertion losses means the filter can stay in place for most any application
The filter is fully EMI shielded, and installed in a custom black 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
Flamingo FM 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
