it being tangentially connected to towers and HF antennas, so hopefully
reasonably on-topic...
Does anyone know if there are SPICE models for filters like the ICE or
NQN, etc?
(yes, it's not that hard to just type them in, but especially if someone
has put in the non-ideal aspects.. ESR, inductor loss, etc.)
it would be interesting to look at the response of the filter, combined
with the coax, and the varying Z of the antenna. Particularly when
looking at things like cosite interference (for field day kinds of
applications).
(or, for that matter, has anyone published S parameters from running
them on a VNA?)
