Customers concerned about mounting a Dish Network dish on their
home should know that the company uses only the highest quality
dishes and that they are installed by highly trained professionals. Like
with any other TV dishes, prior to installation customers can consult
with the technician about the best placement of the dish in terms of
both functionality and aesthetics.
Worries about the installation of a satellite are taken out of the
equation when you subscribe to a Dish Network programming package.
First of all, installation is free, so you won't have to stress about climbing
up on your roof and using power tools to mount your dish. Secondly, the
dish is installed by a trained professional who knows how to properly
position the equipment for the best reception.
Dish Network uses the most technically advanced equipment in the
industry, including the finest quality satellite dishes. This means fewer
malfunctions and repairs. In fact, all Dish Network equipment comes
with a one-year warranty, with a 30-day warranty on labor as well. If
anything goes wrong, your Dish Network retailer can fix it quickly.
When Dish Network first launched their satellite television service, they
used an 18" dish similar to DirecTV round dish. In fact, the dishes and
LNB's where interchangeable. To make use of the channel capacity at
110, Dish Network developed the real first DBS satellite dish for
receiving more then 1 satellite from a single dish. This Dish was called
the Dish 500. It was called so because it was calculated that Dish
Network could broadcast as many as 500 channels using both the 119
and 110 satellites. Technically, they might be able to broadcast 500
channels, but since many of those channels are territory restricted, no
one system could be authorized to receive all 500 channels.
The first Dish 500 Dishes used two-single LNBS for a one receiver
system, but Dish Network quickly moved to using all dual LNB's. A single
LNB only has one coax connection. A dual has two coax connections. To
allow a receiver to get signal from both the 119 LNB and the 110 LNB.
Dish network developed the SW-21 Switch. The SW-21 Switch is a
digitally controlled A/B switch. When the receiver want to tune to a
channel on the 110 satellite, a digital signal using the DisEqC format
was sent down the coax to the switch. Another signal was sent to
switch back to 119.
The next evolution in Dish Network LNB's and Switches were combo
units. The Dish 500 Twin and Dish 500 Quad combined the LNB and
Switch into one self contained unit. These combo units increased system
reliability by removing exposed coax connections from exposure to
weather.
Over the years Dish Network has created several new technologies to
expand the installation options of Dish Network Receivers. The term
legacy refers to the first methods used to send satellite signals from the
dish to the receiver. In the beginning DBS Satellites such as those used
by both Dish Network and DirecTV only transmitted either odd or even
transponders. Each transponders carries as many as 20 individual
channels. A transponder is best thought of as a cluster of channels.
When Dish Network started using a satellite dish which received signals
from two locations, such as the Dish 500, another type of switch was
created. The 2 in 1 out (SW21), and the 4 in 2 out (SW42) switch
allowed a DISH receiver to control a switch that selected either one of
two satellites. Think of these multi-sat switches as electronically
controlled A/B switches. Soon after, DISH released the legacy Twin 500
and the legacy Quad. This LNB's incorporated two LNB and internal
switches, eleminated the need for external switches.
The problem with using a Dish 500 with more than four receivers was
the number of devices needed. Going beyond four receivers per dish
came an exercise in the use of splitters, jumpers and more switches.
Possible but not very pretty, and subject to increased signal loss. This
meant short cable runs between all devices. A new method was
needed to transfer the signals between satellite and receiver when
using the Dish 500.
The next issue facing Dish was their introduction of the dual tuner
receiver. These receivers have two tuners which can provided individual
service to two TVs. The DVR receivers, can also operate in a mode which
provides two tuners to one TV. This allows the user to record two shows
or record one show, while watching another. The only problem is you
need two coaxes installed to the receiver. Many homes are pre-wired
with only one coax to each location. This meant installing additional coax
cables in homes where the home owner was not expecting the need for
more cables. After all, they were told the house was a wired and ready.
Most the time the house not wired properly, but that is another story.
To help solve this problem, DISH developed the Dish Pro Plus (DPP) LNB.
The DPP LNB has three connections. Two for receivers and another for
mixing in signals from another dish. More later. The DPP receiver
connections are unique in that they work on ALL dish receivers. Legacy
and new models. The DPP LNB works just like a legacy LNB. It uses the
950Mhz - 1450Mhz (500 MHz bandwidth). It uses voltage switching
polarity selection, but has another 500Mhz band at a higher frequency.
This upper band is only accessible by a dual tuner receiver. The dual
tuner receivers use the lower band for Tuner 2 and the upper band for
Tuner 1. Each band can supply either odd or even transponders from
either the 110 or 119 satellite. The third port connects to another dish
installed with DP single satellite LNB. This dish is used for reception of
additional DISH programming from satellites at 61.5, 129, or 148.
