We had so-so cable TV reception, especially in an upstairs TV, which I had assumed was a weak signal coming in from the cable at the street. However, the cable guy came and tested and said signal was good from the source. Then, my brother-in-law suggested an experiment: Take the cable at the basement and connect directly to the farthest TV to see if any difference. There was! Moral of the story, and solution: If you have one or more TV connections in the house, there are one or more splitters in between the source signal and the TV you're watching. Each split, and each re-connection of extension cables (e.g., to a VCR), even if the TV connection is not being used, represents signal dilution. The solution is to buy a Motorola Signal Booster ($43 from Amazon) and install at the source of the cable signal. This high quality amplifier strenthens the signal so that it can go past the splitter(s) and through long cables in the house while still retaining enough juice to fully power the TV tuner. It made a very noticeable difference for us! NOTE: THERE ARE OTHER AMPLIFIERS TO CHOOSE FROM. BUT, BASED ON RESEARCH FROM THE WEB, AVOID THE CHEAP ONES!!!
