Tangent
I had an rc submarine that could go underwater a couple feet, but I'd take an rc car's 27MHz radio and put it underwater, it'd stop working almost immediately soon as it went underwater (waterproofed). Wonder what the difference was.

Regarding "longer antenna" for submarines... -- I recently learned about this signal from https://www.sigidwiki.com/ -- which has been helpful to ID all the fun stuff you can see with RTLSDR
Corona, stuff like this, the sheer gall, it's impressive.
