Please avoid using virtual channel numbers, use the call letters for the station as they are unambiguous.

You cannot use the RCA amp in your location. It will overload.

To have any realistic shot at receiving WSYX, all of the following need to be true:

1. The C4V must be aimed DIRECTLY at the station.
2. The antenna must have a CLEAR AND UNOBSTRUCTED view in that direction.
3. You must use an over-load resistant preamp to preserve whatever signals might actually make it off the antenna.

Clearstream 4v is 12.25 dbi max gain puts me real close to 0.
No, it doesn't. You must first correct from dBi to dBd before trying to apply the C4's calculated gain from the TVFool calculated noise margin. Subtract 2.2 from either the gain or the noise margin to compensate.

WSYX's transmitter provides poor coverage out to their northeast due to the drop in terrain in the vicinity of Sparta. Based on TVFool's statistical calculations, your odds of picking it up are, at best, somewhere between "Poor" and "Very Poor".

The looming spectrum repack is one of those things that are expected to eventually happen some time in the future but is still too ambiguous for anyone to really make any decisions yet.
