Thank you for the TVFool report. Here is a rabbitears.info report based on my estimate of your location. It should have a more accurate list of channels.

You can do your own report here. You might need to use coordinates.

Therefore the preamp is boosting an inferior signal....
It is not clear to me where you think that 2.6 dB loss is coming from.

Is it because there is a long length of coax between the antenna and the input of the RCA preamp, or some other reason?
