Diplexer help

[davesrave]

I have three D*TV boxes. One of those is directly connected to my UHF antenna for hidef. Right now, I need to connect the other two to my analog cable system. Eventually, I can see all of them connected to both D*TV and antenna, once all of TV's are hidef capable. The hidef channels off my antenna are even better than what D*TV and the local cable package offer (lucky me). What are the products I need to purchase to accomplish this?

Here you go.
Use a spliter to split the main cable to get enough lines for all your receivers. Run one line of the splitter to your Antenna In port of your receiver (or direct line to your TV*). If you have only one line going to the satellite receiver that carries satellite signal then you'll need Diplexers. Outside, connect one line from the cable splitter to ANT port of the diplexer and one line from satellite dish to Sat port of the Diplexer. Run one line from the diplexer (In/Out) to inside the house. Inside, connect the line coming from outside to another diplexer's in/out port. Connect one line from ANT port to Antenna in of the receiver (Or straight to your TV*) and one line from Sat port to Dish in (in from satellite) of the receiver.

Note: Diplexers may read UHF instead of ANT
*Assuming that your connecting your cable to TV and not through receiver.
