Hey all,
This may be a dumb question...

I have one run of RG6 going from my closet to my sat. box. I'd like to take the output of the sat. box and run it through a modulator back up to my closet for whole house distribution. I've left out many details of my house setup but those that I mentioned are the only important ones. My question is... can I use a pair of diplexers to separate these two signals even though they are going in different directions? I'm aware that this works perfectly for two signals going in the same direction.. just couldn't decide if the actual direction would make a difference. Any help??

If its the modulated signal from SAT receiver, yes you can send it in the opposite direction using diplexers.

So the real issue is that the frequency is different and not the direction the signal is going?

Right, you can't have the signal from the Dish going in two directions.

Ok... thanks!

That was a true Thinking Outside The Box moment!

That was great! It is very seldom that we work with equipment and suddenly realize that we have made an assumption that just seems to be so much a part of how the equipment works that we don't even realize we have assumed anything!

One of my clients has exactly this. I don't remember why they wanted this, but a modulator output upstairs goes back down the line that the sat signal goes up on, then breaks out of the satellite line, goes around the multiswitch, then diplexes back into a line and goes out to the living room TV along with the satellite signal. The same signal goes opposite to and along with the sat signal on two different cables in the same house.

What a pleasing moment it was when I realized this could be done!

(And I hardly ever use exclamation points) !
