After looking through many posts with many people having problems with the D1000 LNB, I decided to post some info on this LNB.

The Dish 1000 all in one three headed LNB comes in two setups, one is for the East coast, this is a D1000.1, the other is setup for the West coast, this is the D1000.2.

The D1000.1 receives satellites 61.5, 72.7 and 77 west, it can not be used for the west coast.


The D1000.2 is setup to receive satellites 110, 119 and 129 west, it can not be used for the East coast.


Each of these LNB's has 4 ports on them, the first 3 ports left to right (with the LNB facing you) are for receivers, the forth port is for a second LNB, this must be a DP type LNB, a standard or legacy LNB, or another brand (like a DTV) will not work.

Now for the tricky part, these LNB's need more DC current the 98% of the FTA receivers can safely supply.

I ran tests on 20 of these LNB's and most needed at least 720 mA at 20 volts DC to run correctly, why do you say?

The 3 LNB's are all on at the same time, (also the forth port is active) and with the special "Bandstacking" used, (I will get to that later) and it has an internal 4 port Diseqc switch, so it needs more DC power the most FTA receivers can supply.

With all three LNB's on and all three receiver ports active with all transponders available at these ports and the internal Diseqc switch, makes this type of LNB a DC power hog.


Now how to fix this.

One way is to use an inactive or active Dish or Bell OEM receiver on the #1 receiver port, this will power the LNB just fine.

The second way is to use the DC power inserter for a DP44 switch,(and only the one for the DP44 switch) this will supply all the power this type of LNB will ever need, you do not need to use the switch as this LNB has it's own internal switch. Another reason why it's a power hog.

A third way was to use a SonicView 360 receiver but those are very hard to find now days, that receiver could put out 1 amp at 18 volts.

Now when using the DC power inserter you must run it on it's own coax out to the LNB #1 port, why?

Because the DP DC power inserters interface does not play well with the tuners in FTA receivers, this could be a big problem as it could burn out or some type of damage to the receivers HD module, it has to do with improper inductance and DC loading to the receivers tuner or HD module, I would not risk damage to the tuner or module, the module is replaceable the tune may not be.

The Dish/Bell OEM receivers can handle this DC interface as they are designed to do so, the FTA receiver is not, it was designed to use one LNB, or several standard or legacy LNB's with a Diseqc switch in-between them.

Also do not use any other type or brand of switch power inserter, the D1000 was designed for the DP type used for the DP44 switch and no others, not even one for a DP34 or an SW44, using any other type may damage the LNB.

Other things to consider when using a DP type LNB like the D1000 series.

Is that they use what is called "Bandstacking" this puts all the "R" or "V" transponders in a second band at a higher then normal frequency, this band runs at 1450 to 2150 MHz, so to properly use the DP type LNB's you must use coax rated out to 2.5 GHZ or swept to 3 GHz or you will have problems with missing transponders.

One good thing about the DP type LNB's is that you can use about 200 feet of good quality RG-6 quad coax between the LNB and power inserter, the same for each receiver attached to the LNB, this is about twice the distance for a normal setup.

With the internal Diseqc switch the switching is setup as follows.

For the D1000.1: East coast
Diseqc port #1 = 72.7W
Diseqc port #2 = 61.5W
Diseqc port #3 = 77W

For the D1000.2: West coast
Diseqc port #1 = 119W
Diseqc port #2 = 110W
Diseqc port #3 = 129W

Diseqc port #4 is open, but can be used for 118W with a second DP single LNB on a second dish, this dish needs to be larger the the standard dish supplied for the D1000.1 or D1000.2,

Now with the #1 port tied up for DC power to the LNB, you only have 2 ports for receivers, if you need to run more then that then the DP44 switch can be used, this will give you a third port for a third receiver, as again the #1 receiver port will be used to run the switch, the good thing is that you can cascade the DP44 switch, you can add two more switches to this setup, this will allow you to run 9 FTA receivers off the one D1000 LNB.

There are other setups for the D1000 system like the Dish 1000 plus but they use the DP44 switch to run them, so follow the connections to run the switch by it self off the DC power inserter and it should work fine.

And lastly be sure to properly ground the system to an approved ground point, by using a ground block rated out to 3 GHz, do not use one for CATV or off air TV, it does not have the frequency range needed to run the system on.
