Need Tech assistance. Need to know how to split signal. |
|
|
I'm trying to run a HD DVR in my living room, but only have one cable drop. The Directv installer said I needed a second drop, but he couldn't do it because it was too hard. I contacted a different company and they quoted me almost three hundred bucks to run a second cable drop. I want a dual receiver DVR, but I don't want to pay that much.
Is there anyway to split the signal on the existing cable drop and still have full HD and DVR capability or am I just going to have to fork over the cash and have someone run the second cable drop? Any help would be really appreciated.
I have the newest oval dish with the built in swith. |

There are no simple tricks. You need that additional line.

Call up DirecTv and bitch loudly. They should do the install, and should
compensate you for the improper install. |

Nope, you need that second line. Anything else would cost you way more that
the $300 the other installer wanst. |

Since I'm in the same predicament with my HR10-250 and living in a condo
with only a single cable line from the electrical room, I've been
researching this problem since May.
Actually it is indeed possible to support a dual-tuner HiDef receiver or
a pair of singe-tuner HiDef receivers over a single cable by stacking
two satellite bands independently. For single satellite installations,
the stacker/destacker combination has been available for some time now.
However, none of them accommodates the extra signaling required for
independently stacking two signals from a multi-satellite dish.
A standard dual-satellite receiver or a multi-switch, in addition to the
standard voltage level to select the left or right transponder of a
single satellite, send a 22 KHz tone to select between the first and
second satellite. This allows four combinations and covers the bases for
the triple-LNB multi-sat dish from DirecTV since it emulates just two
satellites. The new satellites that DirecTV has recently launched will
doubtless require additional signaling combinations. At this time I have
no information on how that is done.
One suitable hardware solution I found comes from Johansson in Belgium,
as described in the technical information at the following link.
Unfortunately this solution is not marketed in the US and may not be
compatible with DirecTV receivers, even though both US and Europe
apparently use the same satellite switching voltages and control
frequencies.
http://www.johansson.be/htmen/stackerdestacker.php?ref=9639KIT
Or see the PDF at this link with nice graphic illustrations:
http://unitron.be/htmen/instrumentarium/is-9639kit-eng-stacker-destacker
%20for%20matv.pdf
The Johansson unit is capable of stacking any one of the possible
selections into either the lower or upper frequency band. Thus one tuner
in a dual-tuner receiver would be connected to use the lower and the
other the upper band. Each tuner could independantly select the desired
band.
That Johansson kit is advertised in the UK for £159 (~$278) here:
http://dastv.co.uk/DAS/Products/ViewProduct.aspx?ProductID=305&RangeNo=7
For the US market, Sonora Designs already markets a stacker/destacker
pair that handles just a single satellite, as described in these two
links:
http://www.sonoradesign.com/dtvsystemspages/dtvsystems_destackers_d575.html
http://www.sonoradesign.com/dtvsystemspages/dtvsystems_stackers_us575.html
After I contacted Sonora, I was informed in mid-November that they already
have produced engineering samples of their HiDef compatible dual-tuner
stacker combination and that they would be marketing it by this December.
Since I don't yet find any reference to it on their website nor elsewhere,
I assume that there's been a delay for some reason.
The pricing for this new stacker combination may be more than the cost
of a second cable run and thus may really only be of interest to those
of us who just cannot install the second cable.
If anyone else has well-founded technical insight into this topic or can
reinforce or refute aspects of my information, please chime in.

This won't be of any use to you as a DirecTV sub (and once you've
purchased an HD DVR, switching sure isn't reasonable). Just thought I'd
just mention that the DISH DPP multisat switches do what your Johansson
reference does by having the switch connect one sat's Odd/Even to
950-1450Mhz and another (or the same) sat's Odd/Even to the higher
500MHz block (stacked). It only works with the DISH dual tuner
receivers (also dual TV output) where there is a single source
commanding the switch for what to put onto high and low ranges of the
single coax, knowing what to expect on the tuner not doing the
"commanding". i.e. it can't supply two single tuner receivers on one
coax. The DPP Twin LNB has the functionality embedded in the LNB for
$40-50 on eBay and lets you feed two dual tuners and has a connection to
feed a 3rd sat location into the DPP Twin.
I'd hope something similar might come to pass for the new DirecTV switch
signaling but also don't have any info.

I heard they stack each Spaceway frequency on top of the regular DBS
satellit IF freqencies, so 950-1450 is regular DirecTV satellites, 1550
to 2050 is the Spaceway sats, each at 0 Khz and 22Kz switching tone (IOW
one over 101, the other over 110/119).

|
Except the Johanssen unit isn't directly DirecTV compatible. The
Johansson unit uses mini-diseq, not a hard 22 khz tone.
You might be able to use that with a combination of traditional
stackers, which significantly adds costs. |
