Well, we can definitely help you! You are very close to your transmitters, so signals are strong. That 8-way splitter in your basement is what's causing you problems. It isn't clear from your post if you have all 8 ports on ths splitter used, or only 4 of them. When you are splitting off to 4 or 8 tuners like that, the splitting and line losses are greater than the gain that the antenna provides, so you are actually in a significant signal-loss situation . This is where a good distribution amplifier will help you. If you are using all 8 connections on your splitter, and powering 8 tuners, then buy a Winegard HDA-200 distribution amplifier and mount it in the antenna line BEFORE the splitter: it will provide enough gain to power 8 TV sets by overcoming cable and splitter losses.
If you only have 4 cables run from that splitter and don't anticipate using any more TVs, the replace the 8-way splitter with a high-qualioty 1 gHz or better low-loss splitter. The 4-way splitter will have considerably less splitting loss that will the 8-way. In any event , I suggest that you use the HDA-200 amplifier to overcome the losses inherent in so large a split. The HDA-200 requires AC power, so be sure that it is available where you mount the amplifier.
Try this solution before you play with the antenna: I think that the amplifier alone should solve your problems.
