04 What frequencies and/or bands are used for TVRO satellitetransmissions?
Satellite transmissions can be received from two different bands:
C-Band and Ku- Band C-Band was the original band of frequencies used
for the transmission of communications satellite signals and is still
the most commonly used band for TVRO use. In fact, the term C-Band is
often used interchangeably with TVRO; unfortunately,
this usage is actually incorrect since Ku-Band TVRO also
exists. C-Band frequencies fall within a range of 3.7 to 4.2 GHz.
Ku-Band is a newer satellite band for TVRO transmissions. Ku-Band
frequencies fall within a range of 10.9 to 12.75 GHz. Unlike C-Band,
Ku-Band has no accepted standard for reception, at least in terms of
channel number assignments. As far as reception, any satellite
receiving system capable of receiving C-Band can receive Ku- Band with
only minimal need for additional equipment. In fact, Ku-Band can be
received with smaller satellite dishes than those needed for C-Band
reception! (More
on this later in the FAQ) Ku-Band is also the satellite band used for
DBS systems (more on DBS later).
