A VERY tight-beamed yagi type antenna might work better. However, I don't know what actual RF frequencies your locals broadcast on, and IF they are within around 30-40 degree spread or not. Run a Rabbitears report at 30 ft, RIGHT from your actual property coordinates (peferably the exact location of your antenna right now) and 100 miles, and post the results LINK here. Do NOT just post a screenshot of the results. The link allows me to click on the stations, and see the actual signal path it has to go through before hitting your house.
