frequency is the signal that is down converted by the LNB. Satellite IF
can be challenging to distribute efficiently, especially in large
buildings, because of the higher frequencies involved (up to twice that
of CATV or OTA) and the need for DiSEqC* and voltage switching. Because
of these difficulties, the Dish Network or DirecTV company technician
often has no option but to install a separate dish for each customer.
The result is often a courtyard full of dish antennas that can't be
removed because no one knows who they belong to. We have solutions for
a variety of situations requiring seamless IF distribution.
Dish Network uses a fleet of their own
satellites to deliver DBS
services in the upper Ku band. A "Dish 1000" antenna or three single
18" dishes is sufficient to supply satellite signal to a building of
For smaller buildings we can supply you with a
master antenna and the
equipment to distribute it in the form of Dish Pro Plus multiswitches.
A single Dish 1000 antenna can supply up to six DPP44 4-output
switches. Each DP+ output can supply one dual tuner receiver for up to
24 separate units and a total of 48 rooms. The example below supplies
12 duo receivers for a total of 24 rooms.
For larger buildings such as high rise apartment
complexes, we can
supply you with a pair of Drake Digital transcoders that convert the
incoming QPSK or 8PSK signal into QAM, delivering all of the satellites
on one cable at one time and requiring no switches. Because the
transcoder also converts the signal to a lower frequency band
(5-900MHz) it can be distributed just like over the air or cable TV
with inexpensive taps, splitters, and distribution amplifiers. In this
configuration tenant are limited to ViP222 or DP811 receivers.
As a courtesy we also offer DirecTV master antenna
service, but because
of the way DirecTV distributes their programming, we can only offer
this service for standard definition. A DirecTV master antenna system
requires only one dish antenna, and with a band stacked LNB can provide
all programming available on the Ku band satellite at 101°W to as many
receivers as needed, using satellite grade splitters and 950-2150 MHz
Our cable headend portfolio includes rack
multiswitches, distribution amps, transcoders, and receivers.
