Question about Dish DVR 510.

Hi,

My question has several parts. First off, we have a Dish DVR 510 connected to a standard TV (as well as to a second standard TV with the use of a set of those special splitter thingies). We are upgrading to a high definition TV and was wondering:

1) Does the Dish DVR 510 pull in HD signals from the dish and output them to my TV?

2) If not, I was thinking of running an antenna for over the air HD local channels... there is a TV/antenna tuner built into the Dish DVR 510. Is it the correct tuner (ATSC) or will it not be capable of tuning the local digital channels.

3) If it does not tune digital OTA, my TV will so I could possibly use the TV's tuner for OTA and the box just for dish content. But in that case, I'd probably like to install the antenna up where the dish is. My 3rd question is, could I use the same wire to carry both sets of signals down to my bedroom? In other words, connect the antenna and dish through a combiner or whatever, and then split it again before the box (one going to the TV, and the other going to the box input). Would that work, or is it too much "data" for a single coaxial cable to handle? It is RG-6, but satellite plus OTA means a lot of channels. Not really sure how that stuff works.

Bonus Question) What the heck is "signal passthru" or "antenna passthru". I came across that phrase a lot when researching this (and still no answer to my 3 questions, just more questions!!) so I'd greatly appreciate a detailed explanation on what passthrough is.

Thank you so much!!!
Cheers,
Jason.

The 510 wii not do anythying with HD,no HD tuner for sat or OTA. You can get local HD from a antenna hook to the TV RF in and the 510 should be hooked up with A/V cables (red white and yellow) or S in place of yellow.
Time to upgrade to HD DVR for your new TV

1. The 510 is not an HD receiver and will not pull in HD.
2. The 510 does not have any type of tuner except for Dish Network sd signals.
3. You would need a set of two diplexers. Make sure you get the correct type to work with OTA and Dish's signal.

Thanks, guys....

There is a TV/antenna input on the 510 so I guess I assumed that was a tuner?? Thanks for the tip on the diplexer... I'll have to look into it. Can the same thing be done for combining cable/OTA on the same coaxial?

Nevermind, I answered my own question about sharing CATV and OTA on a single coaxial cable; can't do it. But I'm still confused about this TV/antenna input on the 510. And what does this whole "passthrough" thing mean? Does it mean that the 510 tuns OTA channels and outputs them to your TV or does it simply act as a signal combiner so you can have a single coax hooked up to your TV carrying OTA plus channel 3/4 which is output by the 510?? Sooo confused!!

No, Pass thru means when the receiver is turned off, any signal connected to that input is allowed to pass thru as is to whatever unit that is connected via the output connection.

Oh okay, so then gary it *is* an OTA tuner?? And it only passes through "untuned" when the unit is turned off? I'm assuming then, in this case, that it is an NTSC tuner and not ATSC (as it is kind of old) so it would be useless for digital OTA. Is this assumption correct?

There is no ota tuner on a 510 (as stated in the previous posts). It allows the signal to pass thru the receiver to your tv. Hopefully your tv has an ota tuner.

Okay, I think I understand. So the 510 simply acts like a "switch" so you can have a single coaxial input at your TV set and the "switch" will alternate between sat and OTA signal (which your TV would need to tune). And passthru in "off" mode must mean that it defaults to OTA when the unit is powered down. Is that right? So the only advantage this has over connecting the OTA signal directly to the TV is that you wouldn't need an additional set of cables (composite or S-vid) going between the 510 and the TV set. Is that right??

You seem stuck on the easy way but not a way for best picture or sound.
Diplexers reduce antenna signal, run a new cable stright to TV.
No reason to run antenna signal VIA 510 no tuner and will also reduce UHF signal.
RF from 510 is poor way to feed any TV.

oljim, I think I agree with you. Here's the setup:

I have coax coming from dish in attic to a junction point in the basement where it goes through one of those special splitters (designed to allow the post-510 signal to travel back to a second TV). From there it goes to the 510 and the 510's output is split to the TV and back into the other special splitter that brings the dish signal back to the original "special splitter" which then goes to a second TV. Gosh I hope that makes sense. If I put an antenna in the attic and want to serve both of those TVs for OTA HD, what is the best way to do so? Should I run new lines for EVERYTHING? Or share the initial downlead with a SAT/OTA diplexer and then new lines out from that initial junction point in the basement? At the very least, the line serving the "second TV" only carries a single channel, theoretically (Channel 3 or 4) so that coaxial could be shared with the antenna signal, right? How would I set that up? I appreciate all of your inputs...

If you get a HD TV get a HD dish rec.
