they look like the legacy lnb, there are two of them

doesn't make much sense. Do you have easy access to the satellite? Can you read what it says on the LNB? or on the satellite. Can you take a picture or something like that?

it's pretty high up and there is no window close to it but i will see what we can do to get a better look at it

in the mean time, thanks for your help, will post it as soon as i have more info

ok good luck

ok so i got a better look at it and it is like the second image you posted, the flat one with combine heads...me bad, sorry about that. i hope now it makes more sense

ok that makes more sense. So it looks like a DPP twin lnb. See if you could read the writing on the front with a pair of binoculars to confirm. If it is a DPP twin lnb then a SW44 will not work, you will need to get a DPP44 switch to add a third receiver.

where do i install the DPP44 switch? after the he grb-2dhr?

Yes, the grounding block helps dissipate the current in case of lightning, make sure both the grounding block and switch are connected to the house ground like grounding rod or pipe. If your installation is near your electric panel then connect it to the main ground there. You can also connect the switch ground to the grounding block as well

do i need to connect both cables coming out of the grounding block to the DPP44 switch or just one?

Yes better to connect both. The diagram is in one of the earlier links I sent.

Note you have to connect both.

I have the sw44 on the dish which is currently only running 2 lines into my house into a central location. From there one line goes into the pvr and the other goes into a power inserter and then into the pvr. For my second pvr I have all the coax run to the same central location. What do I need to get the second one hooked up properly. Is there a way to do it without running 2 more lines to the dish?

Yes. Swap out the LNBF's for a DPP Twin LNBF, then get 2 x DPP Separators, put one behind each Receiver.

Read through the DPP Twin thread as I am sure that will help you understand my suggestion.

I just installed a sw44 switch to a Bell dish with dual LNB's. I have port 1 feeding an HD reciever with the powered inserter installed. Port 2 goes to an older non HD receiver. I have dual cables coming from both LNB's into the sw44 switch. For some reason only the even number transponders are showing a strong signal. None of the odd number transponders show any signal at all?? Sounds like a wiring issue, any suggestions??

What was your setup prior to adding the SW44? Was it working or is this a totally new setup? You have a total of 4 cables coming from the LNBs? Make sure the LNB 91 outputs go to 1a and 1b of the switch, and the LNB 82 outputs go to 2a and 2b. Typically the cable have different colors to distinguish which LNB they belong to. The power inserter needs to be between the receiver and port 1 of the switch.

I would be looking at the connectors between the 82 lnbf and the switch Inputs and also the possibility of a defective Power Inserter (Known issues, that gives this exact problem). Check the 2 connectors at that Inserter too.

As fot Lightbenders suggestion that the cables from each LNBF Typically the cable have different colors, this in violation of the Bell's Installation procedures so the chances of this being the case is or should be slim to none.

I know it makes life easier, visually but Bell frown on that.

Thanks to both Lightbender and Pinza for your suggestions. I think there might be two issues. I'm going to switch the cables as per Lightbenders suggestions. I have also noticed when I turn the TV on now, that I don't even get the even number transponders. However if I unplug the tiny power cable on the inserter and then plug it back in again, the even number transponders come back.
Also to answer Lightbenders question, this was an exsiting system that was working fine. I changed the dish that had one LNB to a dish with two LNB's and added the sw44 switch. I did so to run a second receiver. Back up on the roof I go.

Just ensure you do aiming with NO switch and a direct line from Receiver to 91 LNBF, assuming of course that the Dish is already Skewed and the Mast is vertical.

Ok I tried switching around the cables from the LNB's to the sw44 switch and that did nothing. However when I unplug the small power wire going into the inserter and replug, some times I can get the even number transponders and occassionally I'll get an odd number transponder for just a couple of seconds. It would appear the inserter is faulty but I wonder why it works with only even number transponders, when it does work??

Just got your last response. I should clarify what I have hooked up. LNB 82 goes to port 1a and 1b. LNB 91 goes to port 2a and 2b. I just tried reversing those this morning as per lightbenders suggestion but then I got no reception on any transponders so I went back to original set up. I hooked up number 1 on the LNB, to the 'a' port and number 2 to the 'b' port, don't know if that matters.
The HD receiver is going into port 1 on the sw44 switch and the power inserter is hooked up behind the HD receiver. It's a direct line from the receiver through the power inserter to the sw44 switch. I've changed the short cable from the receiver to the inserter as well, no change. When the even transponders show a signal it's in the high 80's but I get nothing at all on the odd number transponders. Based on this I would think my pointing is good and there is connection to the receiver. Is it possible a faulty inserter would not allow the odd number transponders to receive signal??
Last note port 2 on the sw44 switch goes direct to an older non HD receiver. I haven't played to much with it yet but I don't think I have any picture.
