Yes, the Channel Plus products appear to be the most economical way to go. If I can combine several units, then I know that will be what I need. Thanks for the suggestion. I'm researching other products by Channel Plus, and there seems to be a good selection of products that can do what I want. And since many of them are obsolete now, the prices have dropped, and found several of them at less than $100, so the gerbils in my head are spinning the wheel trying to come up with the best combination for what I'm wanting to do.
You're welcome.
These are the combiners that I used to split into the OTA line with:
Amazon product ASIN B00006JPEA
They do introduce a loss like any other splitter/combiner does, but on my setup I have three of them and didn't lose any OTA channels, or notice a significant drop in signal on any of them. They pass DC too, so my pre-amp works fine with them. I also have a 8-port distribution amp that works fine with them, but the combiners are inserted before that.
For years, I'd used a computer with windows media encoder at my house to stream channels to my parents house and a original X Box with Linux/XBMC on it as a frontend at my parents house, I'd written a small program for them to change channels on their computer for the first year or so and then just incorporated the channel change right into the X Box stuff, so the X Box would boot into a channel list and they could just change channels with the X Box remote. Had two routers with DDWRT bridged together for the wireless connection, needed the control with DDWRT because I was going 350' wireless and also customized a bunch of stuff for the network.
Then I moved to using windows media center wireless with a X Box 360 as a front end at their house for years, [probably ten or so?] but a few years ago I got really bulls$%t with MS over some stuff they were doing with Media Center, when they sent the first Beta of 8 to me, a lot of things I just didn't like at all. So I quit using Media Center and just ran RG6 to my parent's house, the modulators were the easiest/cheapest solution that I could find to add extra channels for them. The only thing I really don't like is that I have three or four sat receivers on all the time for the extra channels, and the modulators, but I eventually plan on setting up one of my C dishes down at their house for them. And the receivers and modulators don't use much power, when I had a computer on 24/7 for streaming TV to their house, it used about $20 a month in electricity, this setup uses only a few dollars worth.
The Channel Plus modulators have some oomph to them, running the RG6 cable to my parent's house ended up being almost 500' because I couldn't go directly to their house with the piping, but the signal comes through nice and clear still. Although, it may also be the distribution amp helping out with that.
I used three separate combiners for my modulators, one for each modulator, [I have three modulators.] If you happen to come across a combiner with multiple inputs on it that looks like it would work, post it up please, it would be nice to use just one combiner, verse three, eliminate a little of the spaghetti wiring I have.
Ah, just saw the post up a few from this one that you posted up, that DA-500 looks like something I may check out.
