Many stations are using secondary antennas for the digital signal right now. 
Some stations are also going to change frequencies when the final switchover 
happens.

Also, some digital UHF transmitters are running at less than full power due to 
limitations in the available AC power. I know this is the case at the Empire 
State Building right now. Once they no longer have to power the NTSC rigs, 
more AC will be available for the digital transmitters.

It is more likely that your digital signal will improve after the switchover 
than it is that it will get worse.
