How could this work, two dishes and 1 OTA antenna? Diplexer

[bertbarndoor]

Hi, I am planning on going with HD Dish Network. I will need two dishes as I am in the extreme North East. But, I also want to use one of those neat OTA antennas that is curved and goes on the dish. Is there a way to combing all three signals into one cable (well, two actually as I will have the dual LNBs feeding my dual receiver). So what I would have is two dishes combing into one signal twice (1 for each LNB) and then an OTA antenna for my locals. Does this make sense?

Yeah, a Satellite switch will be used to combine the signals from the two dishes and a diplexor is used to add in the OTA antenna signals.

Good luck.

Rob- Yes, you can do this and with only ONE cable. The correct use of DPP feeds/switches, diplexers on both ends, and the special dual separator (comes with 622) will permit you to connect both sat inputs of the 622 and your OTA antenna - with only ONE cable downlead!!

Ok, I asked a similair question on another thread, is that possible if you are also diplexing the backfeed?(tv2?) I was thinking that it wouldn', not with the standard 2 output diplexers. Will it?
Because if it won't, there will have to be another cable for tv2. And then theres the problem with getting the OTA signal on THAT tv! man, I just gave myself a headache.

To send a TV2 backfeed through the same cable, you would use a SPLITTER/COMBINER combo (just a set of splitters) to combine the backfeed and the OTA signal, before it gets fed into the diplexor. Just make sure the modulated backfeed is set to a channel that doesn't interfere with any OTA signals in the area. :up

Unless you are in a situation where you are pretty close to the towers, that clip on antenna is pretty useless.

Ok, I've actually used that method for the remote antenna when tv2 was too far from the receiver. So, if tv2 were in a shop outside of the house, and i was trying to combine the remote antenna signal,tv2 AND OTA signal into one line. How would that happen?

Man, now I have a headache. Can you point me to a location where this is depicted graphically? Failing that, is there a way you could describe the combo so that I can paint it up in a jpeg to post? I work well with diagrams, not so well with descriptions. Forget the OTA for now, just the backfeed to TV2.

Here is my current setup, one dish with two cables going to my living room tv downstairs (long run) and one cable going to my bedroom tv, short run.

I want to have one D500 and one D300 combine and sent through the long run to my living room where I will have a Vip622, where the signal will split and go into sat1 and sat2 input. Then, I want to feedback the signal from the home distribution out, back along the main long run to the dishes. Then I want to use the short run to my bedroom with the feedback to the tv. So, in the end, I really don't have to rewire anything, just add some switches, combos, seperators or whatever. Tylenol anyone???

I can't believe I did this. It's way past my bed-time.

Here's a diagram. Grab it before I wake up tomorrow with my sanity and decide to delete it.

I think we need to have another Dish sub-forum for you. Just joking.

There are other sites with plenty of good data, including here at SatelliteGuys.us, but here is another link that has a lot of documents you can download. I think you will find an answer to any possibility by click the following link and then reviewing the Distribution Examples.

2 more things....

1. Backfeeding, I don't see why you could not add two splitters, one at each diplexer so that you could feed 3 signals on one cable (Sat-In, OTA-In, Modulated-Out). However, I would think that since you have two cables going to the receiver, you could use 4 diplexers, 2 on each cable, so that one cable would be Sat-In-1 and OTA-In, while the second cable would be Sat-In-2 and Modulated-Out. I think this last option would have less signal loss then using a diplexer and a splitter. I'm just thinking out loud.

2. I would have to go back and read the various posts from bertbarndoor (Rob?), but I believe he is planning on a Dish 500 for 119 & 110, and also a Dish 300 for 61.5.

So, has it been decided on how to wire this all up?
...(a) A DishPro Plus Twin LNBF for the Dish 500, and a DP Dual for the Dish 300; or
...(b) A DishPro Twin LNBF for the Dish 500, a DP Dual for the Dish 300, and a DP-34 Switch; or
...(c) Something else?

Okay, just found the post, looks like he's going with option (a), and will only have 1 cable going from the outside (dish) to the receiver.

LOL THANKS!@!!

Very enjoyable!

Ha ha, I know. When I am in 'learning mode' I totally obsess until I am fully knowledgable! :

You should have seen me a few years back when I planned a west-coast road trip for me and my friends. I had 4 Excel spreadsheets that each represented different decision paths if we wanted to 'adjust' our schedule 'on the fly'. Ha ha.

 

[SmityWhity]

Well you came to the right place, this is better than the Bill Gates' Mansion!

Are they still your friends after that trip? Indeed, sounds like you obsess! lol

I'm glad someone got some enjoyment out of my insanity.

Ha ha, ya they are...and believe it or not, my planning paid dividends. Besides our car being broken into in San Francisco, the trip went by the numbers and fun was had by all.

 

[Roadwarrior]

Yeah, Zandarkoad, thats exactly how I get the antenna closer to tv2, so it could be just about anywhere. I'm not sure how far that would work, but i've used that method so I could run the backfeed to a shop about 75 feet from the house. I'm just wondering how it would work if you were trying to get an OTA signal to tv2 as well. Can you you have 4 diplexers on the same line? (2 outside, 2 inside), and even so, how WOULD you get it to tv2?

 

[bertbarndoor]

Ok, I have edited the drawing, but I think this is the schematic as needed, correct? (What can I say, I was bored at work and am very anal.) Sooo, does this look right to all of you?

 

[ZandarKoad]

To integrate an OTA, I wouldn't use diplexors, I would use splitters. And yes, you can have tons of splitters on the same line, but keep in mind there is a dB loss associated with each one. Often times the quality of the backfeed is quite poor as a result, but that is solved by switching the modulated output to a lower frequency (eg, a lower channel #). For example, it defalts to 60, and I set it to 21 for a great picture. For the OTA this won't work of course. You may need to include an amplifier somewhere. Keep in mind if you intend to put the amplifier after the splitters, you'll need power pass splitters.
