Couldn't think of a good title---but anyway my question is, Can I run a ota signal and a hdtv d* sat signal to a regular D* receiver ? Then in turn can I run the output from that receiver split it and have one coax go to a regular tv, and the other go to a hdtv d* receiver. Obviously I can,, but will the hdtv receiver get the hdtv signal. Hypothetically, I am using a Hughes hdtv receiver which I don't think needs a diplexer for receiving the combined ota and sat signal. I understand that I can't watch different channels on the two receivers.. Have I made sense? Can this be done. Or must I totally by pass the regular receiver and have a seperate coaxs go to the Hdtv receiver.

No. The coax output of the regular receiver is SD NTSC on channel 3 or 4. The HD receiver needs a connection to the dish signal unaltered.

thanks for the reply Greywolf, but one more thought, if the inital standard receiver is not powered on wouldn't it simply act as a conduit for the signal?

thanks again for your time.

Every receiver I know of turns off its outputs when powered off. In fact, the outputs are the only parts that are turned off. Sat receivers are different from VCRs, TVs and cable boxes in that the latter can use the same types of tuners. What are you trying to accomplish? A high frequency splitter or coax switch might serve your purpose but I'm not sure what your purpose is.

Thanks Greyfox, well it is kind of confusing but hopefully I can explain it. I wired my house when it was built with R6 . The location of the HDTV receiver would be on the ground floor close to the future HDTV because of the component cable connection. The coax comes in from the roof to the second floor in a closet,from both the sat dish and the ota antenna. Currently the sat and ota coax's go into a receiver and the coax coming out is split and sent to the downstairs and other tv.'s from this central point in the closet. So I have only 1 coax going to the location of the future HDTV. I do not have HDTV right now. I hope this makes sense. Since it is just my wife and I, mulitiple receivers are not really necessary. I want to work with the exisiting wiring in the walls, and not to have to run coax on the outside of the house to the ground floor. So that is what I am trying to do.

What kind of dish do you have? Is is round or oval with how many LNBs? How many lines are going from the dish and antenna into the closet?

Greyfox, Sorry for being such a pest---email does have its limitations. I am in the planning stages... for future hdtv I understand what I need in terms of dishes (I think) eliptical dish with 3LBN's etc. I just don't want to have to run an additional coax down the side of the house to the living room if I can use the existing installed wiring. Currently I have 1 coax from a non hdtv dish and 1 coax from ota antenna into closet both go to a current regular receiver on the second floor, then the output from this receiver goes back into the closet to be sent to all the tv's in the house including the tv.'s on the second floor.

For maximum utility, you will need 4 wires from an oval dish to go into the closet. Since changes would need to be made, it's best to add the fifth from the antenna. If you use the present 2 wires, even if you diplexed the antenna signal into them, you could only connect to 2 tuners. With 5 wires coming in, you could put a 5x8 multiswitch in the closet and serve up to 8 receivers.


If you only want 1 HDTV and what you have for the rest is okay, you can use the present 2 lines and run them to the new dish. Use a splitter and 2 diplexers to connect the antenna to each of the lines. In the closet, one line can be diplexed back to OTA and Sat for the SD receiver. The other line can be spliced into the line going to the HD receiver. Another diplexer at the HD receiver will separate into OTA and Sat once more.

jrgo43,


It's funny the things that pop up in my mind. The first receiver in the chain is an SD receiver. If the receiver is off, at least some of these pass the antenna signal out the RF port. That might not be much help for what you are doing but it wouldn't hurt to check and I didn't want to leave misleading information unaltered. HD receivers that I'm used to don't do OTA passthru since they have OTA tuners.
