looks like this will do quite nicely for suppressing interference to the 403mhz band. while the passband doesn't appear to be flat as a table it's flat enough; in combination with an LNA any insertion loss and uneven passing should be easily mitigated.As always, be sure to test your electronic components before deploying to production.. it's not at all clear from the tiny markings on the filter element what it's nominal specifications are.
