I would first focus on getting all the channels from a single direction. Many of the stations in red are from Dayton, and you will need a bigger or more elaborate antenna to get those along with the Cincinnati stations. I would try for real channels 22, 12, 35, 34, 28, 29, 20 and 47 first. Those are all closely grouped and fairly strong.
There are lots of ways to raise your antenna - usually the easiest way is to take advantage of the configuration of the roof on your house to erect a mast. You can get a 10.5' chain link fence top rail from the home center and mount it on your roof with an eave mount, wall mount, roof mount and guy wires, or tripod. How high is the highest point on your roof? You should be able to get above that.
