yes..the seprator is a destacker..the diplexer will not workI want to connect a DVR 625 using only a single coax from a DPP Twin LNB. I know that a separator must be used to feed the two tuners, but does it HAVE to be a DPP Separator? Or can I use a red Holland Diplexer in place of a separator?
Thanks

Are you sure about that? It looks like an ordinary DC-blocked on one port splitter, and they're awful inexpensive. I'll have to hook up a DVB box and see...the seprator is a destacker..

The 625 doesn't come with a separator?
You could try it and see if it works
Someone told me once that they did try it and it did work, but you really need to use a seperator but could try it in the meantime if you do not have a seperator readly available.
If it's a diplexer, please show the board where the in/out port is on a seperator.The DPP Separator is just a diplexer, but it operates on different frequencies than a normal diplexer. Therefore you can't use a normal diplexer as a DPP separator.
Normal Diplexer: separates TV from satellite band (54-806MHz and 950-2150MHz)
DPP Separator: separates satellite band from stacked satellite band (950-1450MHz and 1650-2150MHz)

Pardon?Diplexers are also not Dish equipment, therefore can not be replaced. Just FYI, I was told that once when calling.

Thanks.
you didn't answer the question. Where on the seperator is the in/out port?You know it's only ever used for the separation function. That doesn't change the fact that it is just a diplexer.

Why not just go to a dish retailer or ebay or stop an installer and buy a seperator for a couple of bucks?
I thought that was a rhetorical question.
Given that the innards are just passive filtering networks, exactly the same as a diplexer, there is no reason to think that the port labeled "input" couldn't also be used as an output were a DPP Separator used in reverse to combine 950-1450MHz and 1650-2150MHz bands onto the output (labeled "input").
What function do you think a DPP Separator is performing that is different than a diplexer used for separation, other than the difference in frequency of the two pass bands? BTW, I have a degree in electrical engineering. I take it that you do not.
