One day in the near future, I'm going to swing by the makerspace and grab my "agile" modulator and bring it down to the cafe.
We have half a dozen TVs at the cafe that could be running the #NETV Livestream we're it not for the struggles inherent in wiring up cable to a big old weird shaped building with a bunch of free floating TVs.
But the agile modulator plus a small antenna pushes a strong enough "bleed" signal that I should be able to get every television with an analog tuner in the place running the same video source with little additional effort.
