This may be outside of the scope of what GnuRadio is trying to accomplish and complementary hardware would need to exist, but it would be great if GnuRadio had modules to build a software defined antenna analyzer for impedance matching as well as a software
defined SWR meter. Of course it currently has all the various spectrum analyzers and GnuRadio could easily control something like an external antenna tuner, but it would be great if (with the complementary hardware) GnuRadio could automatically measure wave
reflection and match impedance and for its sources and sinks.
