Awesome video, thanks Fred!  This video spurred an interesting conversation with my step dad who is a retired electrical engineer and a former navy submariner aboard the USS Grouper in the late 50s and early 60s.
For comms in his day they would come up to snorkel depth, 56'  and float an antenna  bouy.
