Antenna Help
 

Here is my signal analysis:

I've tried researching and still can't seem to understand what type of antenna would allow me to pick up these channels. There is a little bit of a treeline to the south and I planned on roof mounting what I need. I can't seem to get a grasp on the gain and if it needs a amplifier on it and so forth.

Thanks

To get Indisnapolis:
Antenna Winegard HD 7698P
preamp tvpramp-1
To add WLFI add a Y5-7-13 and a Jointenna for channel 11.
