how do i split the digital signal for PIP?

My tv requires 2 separate A/V inputs to use PIP. How do I split the incoming signal without affecting the signal strength to STB? Everytime I connect a slpitter, the signal looses stregth and I can't HD out of my STB only digital, not HD. Is there a fix or solution for this problem?

Re: how do i split the digital signal for PIP?

So here is the problem with doing PIP.

 

If you split the signal before the STB and assume the signal strength was strong enough, you now have a wire that needs another STB or digital apapter.  

 

If you split the wire before the STB and plug one end into the STB and the other into your TV you will not get a picture from the other wire.  That wire requires the use of another STB or a digital adapter to display a picture.

 

Does that make sense?

It is just the nature of beast in that when you add a 2:1 splitter, you will lose 3.5dbm of signal strength (more loss per leg the larger the splitter.. IIRC a 4:1 splitter a is 7 or 7.5 dbm loss.)

 

How many splitters do you currently have from the ONT to that STB? Do you have any 4:1 splitters in the path that you could swap with a 3:1 or 2:1 (leaving no open legs)? 

 

I will leave it to someone else to recommeand a MOCA amplifier, but that may be you only possible solution. It would have to be a MoCA amplifier, as the STB requires 1150Mhz to receive guide info, etc.. A traditional signal booster typically does not pass frequencies higher that 850-950Mhz.
