If it is running at reduced power now to work on the new channel 20 antenna, you should see some improvement. If it is not running at reduced power now, your reception will be about the same.

The channel 20 transmitter will be running at a little less horizontal power because it is on a lower channel which requires less power for the same coverage area. Coverage area is important to the companies that are paying for the ads.

If you can not measure it, you can not improve it.
