There are also special manufacturers of cellular none parabolic dish receivers for use in vehicles and different cell structures. In this example satellite tv alerts are obtained with a satellite antenna and directed via a satellite tv for pc decoder container and an oscillator converts it to L-band variety of frequencies that an on-board electronics subsequently converts to the same old frequency usable by way of everyday television sets.

The very large dish length, about 3 – 6 ft, required to run C-Band frequencies of about 4 G Hertz supposed that no longer the majority could own it because of the very exorbitant fee of installing one, and the distance for installation.
One other trouble with TVRO is that the huge dish needs to be portable to hold song of more satellite, due to the fact C-Band satellites carry less channels than KU-band satellites.
