Hi I have bought a new rfs band pass cavity and I am just checking about tuning it .it was advertised to work from 400-500 mhz but when I apply a signal around 480 mhz through it it doesn't seem to improve the filtering .When new do the elements inside need to be cut to suit the frequency .My frequency I want it to let through the filter is around 481mhz ?.I have seen other BP filters here and they have a shorter elements than this new tin .
Thank You,
