Infrared repeaters?

[Icicle]

I have a slight problem, What I need is a way I can extend the range of my RC-1 wireless remote for the Canon rebel xt upto at least 50-75 feet?
are their any repeaters that I cn use or how do you people increase the range?

Sorry if this is in the wrong place.

given that certain brands of TV remotes can trigger canon rebel cameras, I would think a simple TV remote repeater should work here.
