Is a separator mandatory for 1000.4?

[red hazard]

Before getting the 1000.4 installed today, I was on the WA via a DP34 and ran two separate coax cables to my 722K thus avoiding the signal attenuation of a separator. The DNS tech said I cannot use two separate 1000.4 LNB outputs into the 722K. Is this true?

you can run two separate leads from the 1k.4 to the 722k without the separator

But why would you want to?

just answered the question as I have done it a few times due to dishmover prewired for the superdish and or didn't have an extra separator at the time.

Thanks!:up

Not wanting to 2nd guess a supporting founder, but, signal attenuation from the separator? Negligible.

Signal loss would be at least 3dB (50%). That is fundamental physics.

It's not a splitter, its a band separator. The entire band coming into the separator is 950-2150mhz. Coming out, it is 950-1450mhz on one side and 1650-2150mhz on the other side. Since no signal division occurs, signal loss is minimal.

And it is not analog. You will not see the diference. Signal level is not just the rf level, it is ebo or Quality, now.

You're right. Z mismatch and relections are minimal. I previously did not have the DP Plus that I have now and forgot about its added functionality over plain DP. Since the coaxes are already run for the old set-up, I am going to remove the separator.

You're wrong. IT IS analog or more exactly quasi-analog. It is not digital until the output of the demodulator. "ebo" is not a valid term. Eb/No is.

Hmmm. Could separators be ganged? IOW, one separator output run to another separator? That way, a single tuner box could be fed, with the other leg running to a separator connected to a dual tuner box. Save a coax run to the 1000.4. Actually, what I'm thinking is an efficient use of the third output on the dish. Or would I need to use a switch (which could be located inside by the first box). I've already got a couple of extra separators.

Nope it doesn't work that way. Here again it's a band separator not a splitter.

I was pretty sure I was dreaming. Well, switches aren't that expensive.
