Theaterworks ,
If you really want good reception put your RF module in the center of the room in the ceiling . It will be away from any gear and closer to your remote . Like 2ndRick said get some emmiter extensions or get some cat-5 and make your own emmiter cables and you should have enough length to get into the lid . If possible keep it somewhere you could get to it later i.e.( by an in-ceiling speaker , attic access etc.) if service is ever needed .
