The DBS Band
The direct, or digital satellite broadcast band, utilized by broadcast corporations may be a sub-band of the Ku-band that encapsulates frequencies from twelve to eighteen gigacycle per second. DirecTV in conjunction with the Dish Network use this waveband to deliver their signals to alittle satellite dish placed at the subscriber's home. Their satellites orbit with the world during a orbit. The belt the satellites operate from, Clarke’s belt, is called once science-fiction author Arthur C. Clarke, UN agency 1st wrote regarding the fixed orbits of satellites during a 1945 technical paper.
The Remote Frequency
DirecTV subscribers management their tv and therefore the DirecTV from a distance employing a remote. relying upon the receiver and therefore the remote, the waveband to use the remote may well be within the spectrum or operate employing a frequency. Infrared needs the user to purpose the remote directly at the unit, whereas a frequency remote doesn’t need an instantaneous “path” to the receiver to perform. The DirecTV remotes operate within the 418 to 433 megacycle per second bands.
Cables
The cables that connect the DirecTV receiver to the antenna should conjointly meet the frequency specifications to hold the signal. DirecTV needs RG6 cable with associate seventy five ohms ohmic resistance and signal losses at 950 to 1450 megacycle per second. The RG6 cable operates inside the frequency ranges necessary to hold the digital signals from the dish to the receiver.
FCC necessities
The Federal Communications Commission regulates and controls the “air-waves” and allocates frequency bands consequently. DirecTV receivers constitute Title fifteen Device category B devices. Devices underneath this classification should accommodates Federal Communications Commission laws and not operate outside the frequency bands assigned .
