Bandpass filter for uhf television 470-800MHZ

For good reception of uhf tv and digital tv, bandpass filter is a choice for avoiding another signal beside uhf tv channel signal. there are 3 type of bandpass filter that be known , Butterworth, Chebyshev and Bessel filter design.
As shown in this design ,   I am using  http://www.wa4dsy.net/filter/filterdesign.html software online design, or can also using Chebyshev design from http://www.changpuak.ch/electronics/chebyshev_bandpass.php 

Input frequency center for 470-800 MHz, 635 MHz , select bandpass filter or bandstop filter design as menu shown.

after input frequency center, bandwidth of the filter 330 mhz, and the impedance input/output 50 ohms, than select compute parts and the result of filter design will be shown as below.
