I want to send a signal from my satellite box to two tv sets. One is about 50 feet away and the other is about 100 feet. With a cheap amplifier I get a marginal picture on the tv that's 100 feet away. If I make any splits, the quality on the further tv becomes very poor. What's the best way to get decent picture on both sets? Do the type of amplifiers and splitters make a big difference? Thanks.
