[ale] OT: Dish Network setup

[David Corbin]

Technically yes,   But the RF modulator in the receviers tend to be 
pretty poor, and by the time you split the signal, and run it a 
distance, you may not be very happy with the picture quality.

>>The way the satalite dish LNB works makes this impossible.  The coax not only carries the RF signal, but it also carries a voltage that serves 2 purposes, 1 is to power the LNB in the dish, the other is to select between the left hand and right hand circularly polarized signals coming down from the satalite, I think the voltages are somewhere around 14 volts for one polarization and 18v for the other (I do not remember the exact voltages, but they should not be to hard to find with a quick internet search).  So basicly if you connected 2 recievers up to one cable, you would short out the powersupply in one of the recievers.

What this box does is route the appropriate voltages to the appropriate half of the dual LNB such that each of the LNB's is always tuned to one of the polarizations.  It also places the RF signals from each of the 3 input sources on each of the 4 (or 8, or whatever) output jacks, so now each satallite reciever thinks it has its own dish.

>>>I am thinking about running coax in another room this weekend.  I'mcurious as to how to do this.  I have 3 dish receivers.  each one has acable going back to the dish.  I want to move a receiver but I can notmove the coax with it.  I was thinking of splicing into the mainbedrooms cable.  So one feed off the dish will now serve 2 receivers. Is this possible? or nothing like old-fashioned cable?_______________________________________________Ale mailing listAle at ale.orghttp://www.ale.org/mailman/listinfo/ale
