OK, So i installed my HR10-250 HD Tivo this week, but when I did it, I un-hooked the wiring to my secondary receiver (aka the kids receiver) because I currently only have 2 wires running from the dish to the receiver. The dish is way out at hte corner of my property, and running another wire from there would require about 250' of coax. I don't really want to have to do this. Can I add a 3x4 switch inline with just the 2 wires in from the dish. I have done this in the past to feed additonal receivers, but I'm not sure it really worked right and the switches I add seem to burn up or something. They quit working after a while. Is there a specific type of switch I should be using to attempt this?
