A modern system's major components include: Receiver, dish, dish mover, decoder module, feedhorn, and LNB.

Ball Screw vs. Acme Thread - Related to the type of dish mover you choose. The acme thread has become known as the industry standard. It is a mechanically reliable system that will push and pull your dish for many years with minimal maintenance. The improved ball screw arm system adds ball bearings to the nut that moves up and down the threads for added power on big dishes. This offers a smoother, quieter operation and a longer life, especially on large size dishes.

Decoder Module - The decoder module, which fits inside your receiver, descrambles subscription channels for programming that you have purchased.

Dish Mount - It is critical that your dish be mounted on a solid and stable mount to ensure peek reception. Ground shift, wind, and settling can all degrade or prevent clear reception. Different mounts include, pole mount, roof mount kit, tripod, ground bases and so on. The pole mount into the ground is a standard and only steel pipe, schedule 40 or thicker, should be used for any installation.

Dish Mover - The dish mover (or actuator or jack arm) attaches to the polar mount and controls the east and west movement of your dish.

Feedhorn - The feedhorn collects the reflected signal from the dish and sends it to the LNB. The feedhorn you need is determined by the types of satellites you want to watch: C-band, Ku-band, DBS, or all three.

LNB - The LNB (Low Noise Block Downconverter)converts the signal from the satellite into a signal for the receiver. Some feedhorns come with LNBs.

Micro Mesh - Micro Mesh is a breakthrough in the mesh dish industry. Micro-Mesh increases C/Ku-band performance by giving the dish surface a truer parabolic shape.

Receiver - The receiver (or "IRD - Integrated Receiver Decoder) connects to the LNB on the dish and the television, it is the unit that sits on top of your T.V.

Servo Motor - This device sits on your feedhorn and allows you to switch from vertical to horizontal polarities, thus enabling you to receive both odd and even channels.

T.I. & Bandwidth Filters - These filters deliver the best possible picture of every channel, even if your system is affected by terrestrial interference (T.I.), or if certain channels require custom bandwidths.

VCRS Decoder Module - These modules allow access to scrambled signals and pay-per-view programming with monthly or annual subscriptions.
