Make sure you do not exceed 3.7 Volts or 95 mA through the filters. Those
are the maximum rated values for #41 wire in that application (maximum
bundled current). (351 mW) Any sort of DC current will mess up your biasing
too. I would suggest attaching the case of the filters to chassis ground so
you do not have an unintentional re-radiator.
All of this is good stuff, I like your foamy spacers, I like the testing
procedures that are shaping up and the results of that testing.
If you could get your generator down below 0 dBm then you could also use an
SDR as a spectrum analyzer/power meter to look at the insertion loss and
filter curve if you took care of impedance matching.
