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.  https://en.m.wikipedia.org/wiki/USS_Grouper
For comms in his day they would come up to snorkel depth, 56'  and float an antenna  bouy.
