Question About - External Amplified Antenna Signal Distribution

[headfirst]

I currently have a Dish 500 with a DP Pro quad lnb for satellite.
I also have a Winegard Stealth amplified antenna, which is connected to a single IRD in my living room via a diplexer near the ird and a large diplexer-looking splitter on the roof. The antenna uses line voltage from the IRD as a power source.
I want to connect other irds in the house to this antenna and share the local digital signals the antenna is providing.
Can a splitter be added to the cable running from this powered antenna to deliver OTA digital channels to other rooms in the house?
Will there be any degradation of signal strength?
All the other rooms have IRDs and I have more diplexers and splitters, just don't know how to connect it all to share the signal.
Thanks!

Quad LNB has four outputs it supplies a multiswitched signal from two satellites like (110 /119) to four IRD’s

Thanks for your help, but, I think you misunderstood my question.
The existing satellite cabling and signals are perfect. What I'm trying to do is share the signal from the externally mounted amplified (powered) TV antenna to multiple outputs from the DP Pro quad-equipped Dish 500. The antenna is already connected by diplexers to a single cable from the DP Pro quad lnb
At present, I only have my living room tv connected to the antenna and I want to add local digital reception to the other rooms with IRDs in them.
I don't have a Dish sub, that's why I want to view local tv through my sat IRD cable by using the roof antenna.

yes it can if i understand your ? right you will need a DISTRIBUTION AMPLIFIER. something like this.

hope this helps.

Since I already have it connected to one IRD and tv, is it possible to split it out to at least one other IRD/tv by using coax splitters and diplexers, wthout having to add more cables and a distribution amp?

[Sat-Alex]

Yes If you have a Dishpro Twin or Quad LNB then you can use the The DishPro SW34 Switch for up to 12 IRDs Check:hxxp://www.satelliteone.com/support-files/dp/Intro_to_DISH_Pro_Tech.pdf

That was a great read, but didn't help me out. Thanks all the same.
I am simply trying to split the signal from an external tv antenna to muliple dish coax cables. The way it is presently set up. I'm only feeding local signals from it to one IRD cable on my DP quad lnb.

Yes a cable splitter will work on over the air. It the signal is strong enough. Wired 3 TV's off the same unamplified Wingaurd antenae. Good antenae.

I just need to figure out how to place the splitter on the line.
I think if I put it right below the antenna-output and split it off to 4 leads, I can use a diplexer on each line from the DP Quad and diplex it back out in each room.
What I need to know is - will a regular splitter pass voltage through from the original powered line originating in my living room? The way it's wired is, there's a diplexer in my living room, supplying IRD signal and antenna signal, but, on the roof, below the dish, there's a BIG splitter looking deal that (I believe) passes voltage to both the lnb AND the antenna - to power the antenna amp. If I were to put a splitter on the line, directly above the BIG voltage-passing splitter deal, would the splitter pass the voltage through to the antenna?
I think if it did, then then rest of the leads on the splitter would feed the other lnb cables through diplexers.
Did I confuse everyone yet? Am I making this overly complicated?

[Fredneck]

No. Actually the diplexer is what combines your outside signal and the dish signal to connect to one input on your receiver so that you can switch to antennae on your receiver without having to change your TV input Mode. Used to be analog and digital. The splitter will reproduce the same desired effects with a digital signal from an over the air source. Place the splitter after the amplifier. From there split off 4 leads Or whatever you have) to your individual diplexers. It combines the satellite sig with the analog or in this case digital sig. It will work. It will take some time adjusting the wingaurd. We used the existing cable wiring for the entire house and in this case multiple TV's. The diplexer just separates the 2 different incoming sigs. Receives one from your antennae and the other from dish. 2 wires per receiver which are connected to a diplexer. One over the air and the other the lnb.
Thanks to you
I think maybe you have a switcher at the base of your dish. Different from what we are discussing as this actually pertains to the number of lnb's and the number of rooms satellite is additionally supplied to.

Can you get better info on the big looking splitter deal up there ?? I'd like to take a stab at helping you out.....but i'd really like to know exactly what that component is.

[headfirst]

Oneape, I'll have to go up on the roof and check, I've forgotten what it's called. It has a sticker on it that identifies what it is.
I'm pretty sure it's not a diplexer as diplexers only pass voltage through one output leg to the lnb, but none to the antenna, (besides that, it's larger than a common diplexer, about 3" wide by about 1 1/2" tall) it came with the Stealth antenna, specifically to power it. That particular component has to pass voltage to both the DP quad and antenna as the Winegard Stealth antenna has a built-in amplifier that uses line voltage from the living room IRD (with a diplexer in the living room splitting out the antanna and sat signals).
I'll check it soon and post what it's called.

[oneape]

Groovie. I'd be curious as to why you're using that antenna as well. It'll certainly work and i'm not questioning anything about your setup...but unless you're stations are all relatively close and all around you, you'd get better performance out of a bigger and more directional antenna. But..... that too brings about new challenges. Just curious .....

It was given to me by a sat system installer several years ago and I used it as a backup for local channel reception when the rom 3 and rom 10 cards were swapped for rom 101 and 102 cards. It was meant for use when there was no hack available yet for the newer cards (at that time).
It worked fine for the local channels while they were analog. It still works fine with the digital channels. The amplification feature brings in the channels very well.
