YES, THIS IS MPEG4 AND KA RELATED!! THE KA COMES INTO THE STORY NEAR THE BOTTOM
Since I've been tired of hoping that DirecTV would offer SD-LIL here, and wanting the ability to DVR NBC, FOX & The CW (come Fall) programming in SD (I have CBS and ABC via DNS), I took advantage of Circuit City's free Stand-Alone TiVo (after rebates)... but now I need to figure out how to hook my antenna up to the stand-alone... and wanted some help figuring out if my thinking is correct.
Currently, I have a Channel Master 4228 antenna hooked up to a CM Pre-Amp (I forget if it's a 7775 or 7777) sitting about 13 feet off of the ground... the RG-6 coax goes down from the antenna to a grounding block under the house, and then from the grounding block straight into the Den where it's plugged into a Surge Protector (we've had several antenna rotors get struck by lightning before), and then into a power splitter where it feeds an HD-TiVo, the TV, etc...
I also have a DirecTV Phase III dish hooked up to a 4x8 Powered Multi-Switch... which powers two DirecTiVo's and my HD-TiVo (as well as a single SD receiver which is currently deactivated, and hopefully will stay that way).
After I purchased my Stand-Alone TiVo on Saturday, I hooked it up to my SD big-screen in the living Room, and hooked it up to the phone line. Since my antenna has not been run to this room, I hooked it up to an indoor antenna which allows me to watch two channels with varying degrees of PQ, and a few others which cuts in and out. This week, I'd like to run the line, AND activate service (which I'll do even if I can't run the antenna this week). Here's my plan:
What I'd like to do is cut the antenna coaxial line coming from the the grounding block a little before it comes into the house and to my HD-TiVo, and then put a splitter to to send an additional line to my multi-switch. Now, before anyone brings up the fact that once I need to swap my Phase III out for a AT-9 dish, the diplexing won't work, this is one of my questions. If I take the line coming FROM the multi-switch going TO the (SD) DirecTiVo in the room with the Stand-Alone TiVo, clip it, and put a diplexor on it, will I have issues once I need the AT-9 dish even though I didn't diplex using the multi-switch and the DirecTiVo unit is an SD unit, or am I safe?!
Also, if this works, do I need to use a power splitter to send the new line going TOWARDS the multi-switch and my current line going to the HD-TiVo?
The power supply to my Channel Master Pre-Amp is in the Den near my HD-TiVo. Will the power supply in the Den allow me the reception in the Living Room, or will I need an additional part or item in the Living Room?
If all of this works, can anybody tell me a good brand of cheap Diplexors and where to buy them?!
