Why Toroidal ?
There are many other antennas available on the market that offers several satellite capacity for a limited range, designed according to a parabolic equation.

The limitation of these multi-beam satellite dishes comes from its original formula. Only one LNB, which is installed in the center, is in its optimal position.

In other words, the second LNB is not in its optimal position. Therefore, a customer experience rain fade and weak signal strength on the channels that come out of these non-optimally placed LNB.

  On the other hand Toroidal formula it is possible to locate all LNB at its optimal position because of its dual reflector design of Toroidal antenna antenna. Therefore, Toroidal antenna same signal strength and stable signal for all LNB under different environments.

Toroidal 55 (T55)

T55 has the same effectiveness of 55 cm (20 inches) dish for each installed LNB.
T55 can take up to 8 LNBs.
T55 can cover up to 40 degrees of arc (60 degrees in azimuth)
