As many have said, the puzzle text this day
was a bit challenging to parse and understand.
Especially this part of pt 2 was easy to miss:
> In fact, the three T-frequency *antennas* are all
> exactly in line with two antennas,
> so *they are all also antinodes*!
not including the antennas in pt 2 gave an slightly
too low answer.
