pointing dish pro plus twin lnb

[vader2.3]

Hi there , just a little confused as to how to point the dish pro twin lnb. It has 3 fittings two marked as port one and port two then a third as lnb in. Now If I connect to port one and get it on 91, can I plug into port 2 and align it to 82? Its switched internally right? so how do I go about aligning it? Just a lil confused. Help is muchly appreciated satfix peeps!!!!

If you're going to be pointing that dish to pick up 82/91, then 91 settings should be Diseqc 1-lnb type (depends on receiver) DP or OCS-DP; 82 Diseqc 2. The 91 satellite should be picked up with the eastern most lnb, you could cover the other lnb with tin foil when aiming. Check with dishpointer dot com for elevation and skew for your area.

You also should know that you will be pointing this LNB in-between the two satellites.

When using dishpointer you must use the multi LNB selection and use 82/91 for the satellites.

You only need one coax to this LNB from the receiver, (connected to port #1) but you need 2 if using an external Diseqc switch.

If using an external switch*** (why?) then Diseqc port #1 has to go to LNB port #1 and Diseqc 1 will be for 91W, Diseqc port #2 will go to the second LNB output, and Diseqc 2 will be for 82W. (as Fn59 mentioned)

The 3rd connection on that LNB is an input for a single DP dual LNB and only a DP LNB, it would be Diseqc port #3 on a single coax to the receiver from port #1 on the LNB, but will not work with an external Diseqc switch.


*** One thing to also know is the DPP LNB (Dish Pro Plus) will only work with the DPP44 switch, (Dish Pro Plus switch) it doesn't like non Dish type switches and doesn't play well with them, if you are having transponder problems, and are using a non dish switch with this LNB then this is more then likely the cause.

What tp should I use for pointing? 12997 like usual?

And when I hooked up my sv360 e to the dpp it did some crazy stuff, it got stuck in boot on a loop almost. Then I was just reading i may need a seperate sw44 power source to power the dpp. Could that have cause it?

[Terryl]

The standard FTA receiver should be able to power the DPP twin LNB just fine.

The SV360 is one of the few FTA receivers out there that do not need the external power inserter to run any of the Dish LNB's, even the Dish 1000 LNB, that receiver will output up to 1000 mA of DC current.

To find 119 use TP 12457, to find 110 use TP 12224, these are CONUS transponders and can be seen almost all across North America.

Also to properly utilize the DPP LNB your coax coming down from the LNB must be rated to 2.5 or 3 GHz**, as the DPP LNB's use higher frequency's to deliver all the transponders at once, you also have to select OCS-DP or Dish as the LNB type, the LO must be set to 11250 also.

And remember you do not need an external switch with this LNB, one coax directly to the receiver is the best setup.

The re-booting looks to be a software or receiver problem, someone that knows that receiver better than I will have to help you out with that.


** this will be marked on the coax.

Thanx a lot. Ill look into all mentioned tomorow. As for the tp I was pointing this dish at 91 and 82,. Are they the same?

I don't think there are any spot beams on those satellites, so any tp should give you a signal, for the 91 sat anyway. The 82 satellite has tp's that use mpeg 4, so a sv360 probably won't show a signal on some tp's. But if you have your mast plumb and skew is set properly then if you find 91 on the correct lnb, 82 should be there also.

My coax just says 75ohm and its rg6. It does not specify on it about the ghz.
The weird thing is it only did that when I took it outside to point the dish. Maybe my outside outlet is f'd.

Im looking into a jynxbox and going hd. The sv360 has been good. but im wanting to upgrade.

[vader2.3]

So my outside plug was wired wrong. Switched it out and setup my sv360e and used the settings above and caught 91 dialed it in and scanned about 300 channels. My question is tho, how can I make sure Im in between 91 and 82 and picking both up? Is there a way to seperate the two lnbs signal so I can make sure one is on 91 and the other is on 82?

[fn59]

91 should be diseqc 1
82 diseqc 2
lnb type ocs-dp

If the LNB has one large oval eye you can block the left side (looking from behind the dish) with aluminum foil, then you should only have 82W, the same holds true if your LNB has two separate eyes, but if your Diseqc settings are correct (as Fn59 mentioned) then you should be getting 82W when your have Diseqc 2 selected in your satellite settings for 82W.

As far as the pointing transponders, both 82 and 91 have TP 12224 as the default transponder, however the only transponder on 82W that is in SD is TP 12428, it is the only one that is not in 8PSK turbo, it's SR is 20000, and the FEC is 7/8, this is the only one you will find on that bird unless you have the 8PSK turbo card in your receiver.

Hummmmm, that could be a problem, as some coax was only for CATV or off air TV and is only good to 950 MHz or 1 GHz, it has to be rated to 2.5 GHz or swept to 3 GHz, or your going to be missing a bunch of channels, most of them from the higher band.


And if you upgrade to a newer receiver leave the SV360 on port #1, it will power the LNB for the other receiver.

[vader2.3]

thankyou for your help terryl. I think I might rewire the sat with new coax that im sure has the right rating.

I ordered a jynxbox ultra hd, I noticed its power supply is 450 ma as apposed to the sv360e's 1000 ma power supply. Any idea what the dpp twin lnbf power demands are? I cant find that answer anywhere but im just tryin to figure out whether i will need a power inserter or not

[Terryl]

If you only use the one twin LNB and without a switch,(the twin LNB has an internal switch) the Jynxbox should supply enough DC current to run it, and when replacing the coax, see if you can get the good stuff, the good stuff is rated to 3 GHz and has a pure copper center conductor, this will provide less problems.

I always use RG-6 quad with the pure copper center, it may be a bit more cost, but you will have less problems in the future.

If you go out and look for some coax at a hardware store bring a small magnet with you, use it on the center conductor, if it sticks its the cheap copper plated steel center, and be carful on ordering online, there are some very poor quality coaxes out there.

Just be sure it can go to 2.5 GHz or says it is swept to 3 GHz and has a pure copper center conductor, and you should be fine.

Also on pre-made up coax lengths, be sure it has outdoor rated connectors on it.
