Where you require bandwidth at VHF and higher frequencies about equal to a television channel, a good choice of filter is the:
none of the other answers
A TV channel bandwidth (e.g., 6 MHz) is relatively wide. While cavity or helical filters can be designed for various bandwidths, specific types like SAW filters or interdigital filters might be considered, but the options usually given (Butterworth, Chebyshev) refer to response shapes not specific structures for this BW at VHF+.
