Is there any possible use for the third (middle) LNB on an ellipical dish. I noticed that there are now dual and quad LNB devices available.

If you are talking about the DirecTV oval dish, yes. The middle position is for the 110 degree orbital position.


If you are a D* subscriber living in the Carolinas, they havs a special 'Sat C' kit to get the local stations there.


Now, if you want to have some fun, you can convert the dish to use it with Dish Networks and DirecTV at the same time.


By putting a regular (NOT Sat C Kit) LNBF in the center position and adding the right switches, you can get it to pick up:


DirecTV - 101 (main) and 119 (HDTV, locals & Espanol)

Dish Networks - 119 (main) and 110 (AT150 extra channels, locals)


I have an article on what I did to accomplish this at http://www.techweenies.com/dss-1.shtml


At the end of the article there is a link to another excellent site that has diagrams of all the possible hookup combinations.

Hmmm, why did you want basic programming for both Dish and DirecTV?


I'm using two regular dishes:


1) DirecTV 101 (basic programming, NFL Sunday Ticket)

2) Dish 148 (HDTV: HBO and Showtime)


I have an oval dish sitting idle in the garage. Am I missing anything major, considering that I don't have a DirecTV HDTV receiver for HDnet? Any reason I should want Dish basic programming, considering that I already have DirecTV basic programming?

Thanks very much!


I had a lot of fun with the project and putting it together. One change I would make to the project as it stands is to recommend using a SW44 with the SW21's or a SW64.


It appears that, in practice, the SW42 really doesn't like to be cascaded with the SW21's and the signal-split multiswitch. Not enough power, I guess.

No, the images are only on the Techweenies.com server. I just went there and they come up fine.


Now, they *are* a little big. If you are on a slow connection, you might have to wait or reload the page.

The problem with the images is a problem with the website and ns4.7. I'm pretty sure it's caused by the <ilayer> tag causing ns4.7 to hit a bug with figuring out what the base URL is. It's trying to fetch the images from banner.clickfinder.com/banner/images/* . You might fix it by adding a <base href=" http://www.techweenies.com/dss-1.shtml"&gt ; tag, or removing the <ilayer>.


This problem does not exist with ns6/mozilla and probably doesn't in IE. (Layers are a netscape-only thing that was dropped from NS6 and Mozilla.)

Someone still uses Netscape? http://www.avsforum.com/ubb/smile.gif


OK, I put in the base href tag, so you should be able to see the pics now. Can't remove the ilayer tags, as they are part of an ad and I am not supposed to change the code.


Del, yes you can use your Dish 500 dish to pick up DirecTV's 101 satellite as long as you do not have a Twin or Quad LNBF. Those have switches built in that aren't compatible.


You will have to connect the DirecTV receiver directly to the LNBF, bypassing any switches you may have had in your system.


What you won't be able to do (well, not easily) is pick up both DirecTV orbital positions at 101 (main) and 119 (HDTV, locals & espanol). The Dish 500 isn't made for a 18 degree spread from 101 to 119. It is made for a 9 degree spread from 110 to 119.


But, as long as the LNBF's are compatible, there is nothing to prevent you from re-pointing it at the 101 satellite for DirecTV. Use the same elevation and skew as you would for Dish (or if the dish is still installed, leave it alone) but loosen the bolts that hold it on the post and sweep the sky slowly until you get a signal.


Once you lock in on the sat, you can fine tune it but the main thing is going to be the azimuth.


Good luck.
