Hello All
I have noticed that my LNB with 20m of coax overload my frontend Kenwood TS-711E with 2 S-units or 12 dB. If I push the ATT button the RX-noise goes away. The ATT has an attenuation of about 30 - 33 dB. Now my question:
If I put an attenuator like this one with >12dB in between TS-711 and downconverter is the SNR better or the same as I push the ATT button (-30dB) ? Will the SNR decrease with more attenuation ?
Tnx & 73
