View Full Version : DishPro LNB's and Switches
What is the difference between the Legacy and the new DishPro LNB's and Switches. :confused:

Thanks.

DishPro is a new technology that uses bandstacking, i.e. Horizontal Polarity is on one frequency band and Vertical polarity is on another band. Legacy LNBs and switches use the same frequency band for both satellites and use voltage for switching. You cannot mix and match DISHPro LNBs and Switches with Legacy LNBs and Switches. Also, with DISHPro, you need to use special adapters with non-DishPro receivers. DishPro receivers include the 301, 501, 508, 721.

Since Dishpro requires 2.2Ghz frequencies, the coax, the grounding block, F81 connectors, and "F" connectors must be able to handle such high frequencies without losing the signal. Bad connectors, nail pinches, DG59, old corroded coax, and kinks in the coax will likely cause problems for those using the new DishPro technology.

So, then, do the DISHPro IRDs work with the legacy LNBs and switches? For example, if I wanted to replace my DISHPlayer and 4000 with a couple of 501s would I have to replace the LNBs and SW42 as well?

Yes, all DishPro receivers, 301, 501, 508 and 721 works with legacy lnb's and switches. DishPro lnb's and switches require an adaptor for each non-DishPro receiver.

No, you will not need to replace your LNBs and SW42. They will work with your 2 new 501s just fine.

Does anyone know if the external adaptor units, commonly called destackers or subscriber units, are now available for the DISH receivers that cannot internally destack, and if so, what are their part numbers and how and for what price can one obtain them?

Wait a minute. Does that mean that these things will tolerate line splitting? With D* if you run a stacked system you can split the feed lines (with a power pass splitter) and send them to two destackers or recievers with internal destacking capability. Or to one dual tuner PVR. If so, that is sweet and will make 2 tuner PVR installs a whole lot cleaner and easier.
Do they????

Yeah, they make a destacker for lagacy "non-DishPro" dish equipment. They are not avaiable yet to date. Only the DishPro lnb's are currently available, separately, and with the DishPro 721. From other dealers, I have heard that the 721 has had problems with compatibility with the DishPro twin lnb and the DishPro lnb has ran hot.:shrug:

You will not be able to use any old line splitter with DishPro. They have proprietary SW34 switches. They can be cascaded for more than four ports. Basically, they will allow three coaxes max to the switch (eg. 65.5, 110, and 119) and one out to each receiver. I am not able to post some info on DishPro switches, since it is confidential to Dealers and Echostar. Some 80% of the currently installed coax, almost all F-81 barrel connectors and grounding blocks will have problems of the 2.2Ghz signal used by DishPro.:(

If you only need the core programming, then it seems to me that you could split that single coax using a high frequency splitter

More accurately, some 80% of the currently installed coax and almost all F-81 barrel connectors are not rated for 2.2Gz operation, and therefore might cause problems, but realistically, I have never had any coax trouble with any RG-6 coax that I have used in DirecTV stacked systems that go up to 2.025Gz, and virtually none of that cable was swept for 2Gz. In fact, a lot of it was probably swept for 1Gz.
I'd definitely replace all of the old F-81s and grounding blocks as a defensive maneuver, however. The cheap ones only make contact with the center conductor at two points. The ones markets as 2Gz or higher make better contact and only cost about $.40 each.

The question is who would want to spend $75 for a stacker, so that he or she can avoid running two lnb lines for 119, just to be able to use a splitter? Most people already have two lnb lines going to the grounding block. A 3x4 multiswitch costs $20-25 dollars. Also, they do not make a dual DishPro lnb for use with a stacker. Furthermore, the DishPro equipment is proprietary to Echostar. So, a stacker like the Sonora probably will not work with a single slot dual lnb and a stacker.:(

Me.
I service a 180 unit luxury condominium that was prewired with a single strand of RG-6 that goes directly to an eight-way splitter in each unit (smooth planning, huh?), and there are a lot of wealthy Arabic speaking unit owners there who would like to be able to watch more than one Arabic channel on different receivers at the same time, and there are also wealthy Spanish speaking residents there who would like both polarities of E*'s 110 satellite at the same time. Having paid $700 per square foot for their floorspace, they wouldn't bat an eyelash at the cost of putting in a stacked LNB and destackers for what little use they might get out of it when they are occasionally in this country. Believe it or not, the ambassador from Kuaitt did not have me furnish his unit with the Kuaitti News channel, however.
For some of these residents, I will be diplexing Comcast cable with an A/B tone switch that they will mechanically toggle from their apartment to select between stacked Telstar T-5 and a stacked E* foreign service of their choosing. For others, their tone switch will toggle between the E* 110 stacked satellite and the D* 119 stacked signals for more Spanish programming options. I have been stalling these customers for about a year, telling them that E* was going to furnish proprietary hardware any day to meet their needs, rather than have me kludge something together with a Sonora stacker and destacker to accomplish the same thing. I will be visiting one of those customers tomorrow, and will probably tell him to go ahead and buy a dish receiver that comes with a stacked LNB and destacking receiver, and I'll have him "donate" his dish to the building so that other residents who want just both polarities from the 61 or 110 degree satellites can be sourced by it.

I was thinking along the same lines. Makes installs kind of difficult when you have to tell someone with a multi million dollar custom home that he is either going to have to deal with a wire running along the outside of his house and along the baseboard for the #2 line for a dual tuner PVR or cut holes in his faux finished walls to run the wire. With a stacked system you can use the single cable prewire run to carry signal for both tuners.
They need to make stacking/destacking equipment cheaper and more reliable as these issues are what make 2 tuner pvrs such a hard sell for many.
