I had a dilema that I wanted to hook up one of my RCA UTV receivers to work on two different tv's in two different rooms. I bought a set of cones thinking that would solve the problem, but every time my central air or furnace would kick on, they would go berzerk and the cones would change the channel and even erase tell the UTV to erase programs. Needless to say, that just wouldn't do. I came across this searching Yahoo: TERK LF-RCA RF Remote Control Range Extender for use with RCA DSS http://s1.amazon.com/exec/varzea/ts...081/qid=1026018040/sr=1-3/104-7190627-9944737 It is an adapter that fits over the end of the RCA remote that is a sender unit and a receiver that sits near the reciever. It works great. Just thought I'd share. I bought mine off Amazon.com and entered LF-RCA in the search and three sellers came up. I bought mine for $31.99. Much better than the cones.
