DPP twin only on 91 - Canadian TV, Computing and Home Theatre Forums

despe666 · 2012-08-09, 10:43 AM

Hello,

I was wondering if a DPP twin LNB could be connected to an 18" dish, with only the 91 side of the LNB connected to the arm, and picking up only 91 signal.

Here is the situation. My mother has a 5900 that has failed (losing signal every few seconds, I've read that several other people have experienced that problem with that receiver). I looked up on Kijiji, and a used 9241 is only slightly more expensive that a used 5900 for some reason. So I would like to get her a 9241 with as little work as possible. So I would like to use her existing, 18" dish single drop with DPP, and since she only has SD TVs, no need for 82 signal.

Thanks

You can probably get the proper 20" Bell pan on kijiji or craigslist for free.

It won't look pretty doing it the way you suggest and the weight of the LNB may be too much for the 18". The DPP twin is designed to work at the focal length of the 20" dish. Not to mention the pan geometry is different.

Don't even go there, wrong dish for the application.

Maybe it's not the 5900, but the dish's LNB instead???

Or maybe the dish has gone out of alignment.

Before going to all the trouble, try this;

1. Unplug the 5900 from the electrical, wait a few minutes, plug it back in, and let it reboot.

2. Once it has rebooted, do a Check Switch test, by using the remote, press MENU,6,1,1

3. You will now be in the signal strength window. Go to Check Switch and select it, then go to Check or Test and select it.

4. Let the receiver do the tests.

5. Did the test pass (indicating 91 ODD EVEN) or did it fail? I presume from your post that your Mom has an 18" dish pointed at 91.

What are the results? Then we can offer suggestions and go from there.

You can still watch HD programming on an sd tv.

I think it would be less work to use a 20" dish with the DPP LNB than it would be to try to make the DPP LNB work on the 18" dish.

If you only need 91 and only have an 18 in dish what is wrong with just using legacy lnbs like they normally take? If you must have a dpp twin then definitely save a lot.of PITA and get a 20 in dish. I've personally never seen how a 9241 will work or not without both satellites though.

I will be installing 4 x 9241's on Thursday with just 91 signals to it.

Customer (Commercial) wants it that way. He has an existing 18" Dish, which cannot be replaced, so I will just use the 2 lines existing and add an 8 Way Multiswitch, no big deal at all.

It is waaay easier to just use a 20" dish with a DPP twin, and use the one existing line for the 9241, than it would be to rig an 18" dish with a DPP twin, or use the 18" dish with the legacy LNB and have to run a second line to the 9241. If there are already 2 lines to the receiver, that is a totally different story.
