Installing Dish over existing cable wiring

[Drew B]

I need some advice on how to install my Dish after I move to a new home.
The new place was previously wired for traditional analog cable in five
rooms--the cable came into the house, and then was split up accordingly. I
don't know if the cable went through a single main splitter, or if it was
split along the various runs (I suspect the latter, since this would keep
the signal stronger.)

I only have one Dish receiver (which is fine because I have one main A/V
system) but I do have two other TVs that I watch infrequently.

A few questions:

1. When I install the Dish, I'm bypassing all the existing wiring and
having a short RG-6 run come straight from the Dish to the
receiver--probably about 40 feet maximum. THEN, could I use the all the
existing wiring in reverse and use the RF feed from the Dish receiver to
pump Dish Network throughout the house? (I know, I know, this means all
the sets have the same channel and I can only change channels from the
Dish receiver. That's all cool.) I see no reason why this WOULDN'T work,
but maybe I'm missing something.

2. If #1 does work, would there be a way to implement lifeline cable into
the equation with an A/B switch? What's the story with diplexers? Are they
useful, or should they be avoided like the plague?

Any advice or insight greatly appreciated!

hmmm..I really cant help you there...my folks had their house built...and
had cable wire run to every room like normal. When they had E* come out to
do a dish mover...the guy simply ran the dish cable to the house's cable at
the entry point..and interfaced them. My folks had 4 recievers with 5 room
cable hookups so still had 1 more "cable" left to use. Then went upstairs
and just simply plugged the reciever into the wall's cable plug-in.
Presto...Dishnetwork! Made it nice and neet.

Nope - that'll work just fine.

1) should work

2) The A/B switch should work as well to switch between cable
TV and the ch. 3 output of the sat receiver.

Although you don't need diplexers, they are used to combine/
separate a satellite intermediate frequency signal (the 1-1.5GHz
signal from the LNBs) with a lower frequency signal, such as
off-the-air TV or cable TV. Diplexers work fine. A neighbor just
had two put in with his Dish installation. Two of them were put on
either end of ONE coax to run a sat IF signal down to his sat receiver
and a cable signal up to an upstairs bedroom TV receiver. It had
never occurred to me to use a diplexer to pump signals of two
frequency ranges in OPPOSITE directions.

At the rear of your Dish receiver, you have a jack labeled "TV
Antenna/Cable In". Hook your "Lifeline cable" coming from the street to
that jack. Below that jack is another jack labeled "TV Set Out". Hook
your existing wiring to that jack. On your remote, you will find a
button labeled TV/Video. This essentially controls a built in A/B switch
in the Dish receiver. Pressing it one way will feed your "Lifeline
Cable" to the rest of the house bypassing the Dish receiver output.
Press it again and it will feed the Dish output to the rest of the house
by passing your "Lifeline cable".

I use a similar approach in my house except there are two of us with 5
TV sets so I have two Dish receivers. I have Comcast basic cable (25
channels) for $12.75 a month while everything else comes from Dish.
