<p>A floating antenna system which can be deployed and retrieved by an underwater diver is equipped with a pressure proof radome (14) atop an elongated support stalk (12) carrying a lobed, inverted pyramidoidal flotation collar (16) below the radome (14) which can be folded and wrapped transversely around the support stalk (12) like an umbrella when deflated. The air supply for inflation is carried in a pressurized canister inside the support stalk (12). The collar (16) is inflated via an inflation line from the canister controlled by a manually operated pushbutton valve. The antenna (100) inside the radome (14) is connected to a long tether cable (112) which can be connected to a separate receiver or transmitter below the surface. The tether cable (112) can be manipulated to control deployment and retrieval of the floating antenna.</p> |
