Why TV transmission is carried out in the UHF and VHF bands?
Answers were Sorted based on User's Feedback
Answer / sreeram
The main advantage of UHF and VHF transmission is the
physically short wave that is produced by the high frequency.
The size of transmission and reception antennas is related to
the size of the radio wave. The UHF and VHF antennas are
stubby and short. Smaller and less conspicuous antennas can be
used with higher frequency bands.

A television transmission requires a wide bandwidth - very much wider than that of an audio transmission.
The bands reserved for audio broadcastin, both m.f. and h.f., are much narrower than the bands allocated for television; too narrow to accommodate even a single station to operate satisfactorily.
The v.h.f. and u.h.f. bands allocated to television are wide enough to accommodate several television transmissions.
