Satellite Dishes

Ku band satellite dishes usually range anywhere between 18 inches (40cm) to 1.2m (48 inch). Most Free To Air FTA dishes are Ku band. C band satellite dishes can also be used for FTA. C band dishes are are larger in size. Usually 1.8 meters | 6 feet and larger. C band dishes are usually prime focus. With a Ku band LNB specially designed for a C band dish, you can use a C band dish to pick up a Ku band signal.

The difference between the offset satellite dish and prime focal (prime focus) dish is the way the signal reflects from the surface and where it gets concentrated.

Prime Focus Dishes, the signal reflects from the satellite dish and concentrates towards the center, where the LNB is mounted to catch the signal.

Offset Dishes are designed with an offset angle. Usually set at 21-degrees. With this design, the signal reflects from the dish and concentrates towards the bottom of the satellite dish instead of the center of the satellite dish. See the pictures below:

In most cases, there are standard size satellite dishes. See the chart below:

*Because of marketing, some dish manufacturers and distributors advertise an 80cm dish as a 33" dish rather than a 31" dish

The standard size for offset dish lnb bracket | clamp is 40mm

We carry a few different type of HH motors for offset Ku band satellite dishes. Go here for our satellite motor section.
