I have an SDR (RTL2832u) that connects to an antenna and can receive over the air just fine. I'm wondering if the signal of a home cable connection would be too strong to connect to the SDR input or is it safe?
Say for example my home cable modem transmit power is 35dBmv. Downstream power is showing around 10dbmv. Is this too much RF energy to feed into the SDR's antenna input?
EDIT: My capture card uses the e4000 Elonics tuner. datasheet.
