DIRECTV System Components
There are three main components of your DIRECTV System. They are the satellite antenna, the digital
satellite receiver, and the remote control. Take a few minutes to read about each of these components.

The Satellite Antenna
The satellite antenna is the component that receives the digital signals. It must be mounted to a solid
outdoor surface that allows a clear view of the southern sky.
outdoor surface that allows a clear view of the southern sky.
The reflector is also known as a “dish.” At the end of a tubular arm
that is attached to the dish, there is a low noise block (LNB). The
mounting bracket and base make adjustments easy during
installation. Once the dish has been properly positioned to point
towards the satellites, you should never need to adjust it again.

A satellite antenna is provided in single satellite DIRECTV Systems
and multi-satellite DIRECTV Plus Systems. The 18” DIRECTV
satellite antenna model is included with the HIRD-B2, HIRD-B3,
and HIRD-B4 satellite receivers. The DIRECTV Plus satellite
antenna is included with the HIRD-C2 multi-satellite receiver.

DIRECT systems will have either a single LNB or a dual LNB. The
single LNB has one connection, allowing use of a single digital
satellite receiver. The dual LNB has two connections, allowing use
of two digital satellite receivers, or more if you are using a switching
distribution box. DIRECTV Plus systems utilize a special LNB
configuration, which actually consists of two distinct LNBs.

DIRECTV Plus systems have an LNB assembly that consists of two
distinct LNBs. One of the LNBs receives programming from the
primary DIRECTV satellites while the second LNB receives the programming that is offered to owners
of dual satellite systems only. Each of these LNBs can be either single or dual type. The single LNB
configuration has one connection, allowing use of a single digital satellite receiver. The dual LNB
configuration has two connections, allowing use of two digital satellite receivers. The signals from the
two distinct LNBs are combined through the use of an HSWH switch included with DIRECTV Plus
systems.

The Digital Satellite Receiver
This digital satellite receiver is one of the smallest available. From the front panel keys almost every
feature of your receiver can be accessed.
