If you are going with two antennas. One for local. and one for Baltimore, lets start with the easy ones. Use an RCA ANT751 aimed toward Harrisburg, with no amplifier. This should receive All of Harrisburg, and your York/Lancaster stations. You may need to play with positioning, but lean towards Harrisburg if you want WHTM. The signal for WHTM is not what is showing on your report. It is a little weak in Red Lion.
For Baltimore from your attic, the 7694 antenna may not be enough to overcome the -5.8 db showing up for WJZ or WBFF. You could try a more powerfull amplifier. I am not a huge fan of installing a high gain amplifier to make up for an antenna with not enough gain, however a Channel Master 7777 with 30 db gain verses the 12db from your Winegard may work . A much easier fix, worth trying. When you go to the two antenna system you will need to run seperate coax and use an A/B switch. DO NOT COMBIND ANTENNAS INTO ONE COAX. You can pick up the 7777 at Cumberland Electronics in Harrisburg. 888-501-9658.
