Hello. I just purchased two units (both housed in the new black boxes). I have clear sky access from an open south window and can pull in 8+ SNR on the first unit I received. On the 2nd unit, in the same position and same power source, I can barely get anything over 0.23 SNR.
Everything was replicated in exactness but the SNR will not increase to anything resembling an acceptable level.
What can be done to remedy the problem?
