Includes

• 1x RTL-SDR Blog Broadcast AM High Pass Filter
• 1x SMA male to SMA male adapter

Blocks the broadcast AM band between 0 kHz - 1.705 MHz with about 60dB's of attenuation. Pass band is from about 2.5 MHz and above.

Insertion loss is less than 2 dB, and mostly less than 0.3 dB between 5 – 30 MHz. 

Uses SMA female connectors. Comes with a free SMA male to SMA male adapter.

A broadcast AM block high pass filter can help if you have very strong AM broadcasts in your area that are overloading the SDR dongle. 

This is a HPF and not a notch, so it does not pass VLF/LF either. This is an RX only filter.

Perfect for RTL-SDR dongles that use direct sampling or an upconverter, or any other SDR that needs some help with filtering.
