I have RTL-SDR Blog Triple Filtered LNA. I will do following RF Scans this weekend and post their results:
- Scan 1: FA antenna + $9 Generic Dongle
- Scan 2: FA antenna + FA filter (Light Blue) + $9 Generic Dongle
- Scan 3 : FA antenna + Triple Filtered LNA + $9 Generic Dongle.
For the time being, here are the scan results using different combinations of filters & dongles using Noise Source. The last one is for Triple Filtered LNA
