If I were to install 2 antenna's with one pointed toward 215 mag and one at 114 mag it looks like I could install Channel Plus NF-470 Notch Filter onto the HD7697P which would notch the 499.25 - 523.25mHz signals from the 215 mag antenna - but then I would need to figure out how to insert just the channel 23 signal from the antenna pointed at 114mag allowing me to pick up FOX.

However, I'm not sure how much attenuation the filter provides for the notch - nor how to insert just ch23 from the second antenna.
