Radar technologies are detecting smaller and smaller
Submarine communications masts are no exception, and
is my solution:
A water vortex in the ocean. Water is spun and spun into
maelstrom, creating a vortex of air below the surface of
ocean. The communications
mast can be deployed
pocket of air allowing for communications with satellite,
assuming a satellite is in the right position. This leaves
radar signature, the trough in the water not registering
because water absorbs the radar waves.

||It will increase visibility if there is a surface ship or
aircraft doing a visual inspection. I am also not sure
if it is possible to do this without producing a
distinctive sonar signature. Both of those being
said, the idea definitely has some promise.
You could use electro magnetism in something resembling a distributor cap to diamagnetically repel the water and create the vortex. This would produce little to no sound which is good, and nothing for radar to catch which is good, but wouldn't sonar pick up on a vertical column of air rising through the water?
||Is something like this worth the time and money? I
suppose it depends on how pervasive radar is,
compared to sonar. As far as sonar picking up a
vertical column of air, it wouldn't be more than a 4
foot column of air, or even smaller depending on the
size requirements of the com antenna.
||Given that submarines generally try to evade detection, creating a big swirling vortex of air and water is probably a bad idea. Floating a small aerial on a buoy to the surface and then reeling it in after use would be a cheaper and better approach.
