The present disclosure provides a device for providing connectivity to a balloon network. The device may include a sealed vessel partially filled with a liquid. The device may also include a floating base that is comprised of a material that is positively buoyant in the liquid. The device may also include an antenna coupled to the floating base. The antenna may be configured to receive and emit radiation. The antenna and the floating base may be positioned within the sealed vessel, and the floating base may be configured to position the antenna such that the antenna emits an emission pattern that is substantially perpendicular to a surface of the liquid.

1. A device comprising: a sealed vessel partially filled with a liquid;a floating base that is comprised of a first material that is positively buoyant in the liquid, wherein a bottom surface of the floating base is substantially planar;a weight coupled to the bottom surface of the floating base, wherein the weight is comprised of a second material that is negatively buoyant in the liquid; andan antenna coupled to the floating base, wherein the antenna is configured to receive and emit radiation, wherein the antenna and the floating base are positioned within the sealed vessel, and wherein the floating base is configured to position the antenna such that the antenna emits an emission pattern that is substantially perpendicular to a surface of the liquid. 2. The device according to claim 1, wherein the liquid is one of water, mineral oil, or a saline solution. 3. The device according to claim 1, wherein the floating base is coupled to a perimeter of the antenna. 4. The device according to claim 1, wherein the antenna further comprises: a radiator configured to emit radiation according to a feed signal; anda reflector coupled to the radiator such that there is a separation distance between the radiator and the reflector, wherein the reflector is configured to direct radiation emitted from the radiator such that reflected radiation is characterized by the emission pattern. 5. The device according to claim 4, wherein the radiator comprises a first panel positioned above a second panel. 6. The device according to claim 5, wherein a separation distance between the first panel and the second panel is less than the separation distance between the radiator and the reflector. 7. The device according to claim 4, wherein the antenna further comprises: a linkage configured to adjust the separation distance between the radiator and the reflector. 8. The device according to claim 1, wherein the antenna is configured to receive radiation from a region defined by the emission pattern. 9. The device according to claim 1, wherein the antenna is configured to transmit signals to one or more airborne radio stations. 10. The device of claim 1, wherein the antenna extends vertically from a top surface of the floating base, and wherein the weight counterbalances a weight of the vertically extended antenna. 11. A device comprising: a sealed vessel partially filled with a liquid;an antenna configured to receive and emit radiation;a floating base having a first side and a substantially planar second side, wherein the floating base is comprised of a first material that is positively buoyant in the liquid, wherein the first side of the floating base is coupled to the antenna and the second side of the floating base is positioned to float on the liquid inside of the sealed vessel, and wherein the floating base is configured to position a base of the antenna at a non-zero angle with respect to the liquid such that radiation is emitted from the antenna at the non-zero angle with respect to plumb; anda weight coupled to the second side of the floating base, wherein the weight is comprised of a second material that is negatively buoyant in the liquid. 12. The device of claim 11, wherein the antenna further comprises: a radiator configured to emit radiation according to a feed signal; anda reflector coupled to the radiator such that there is a separation distance between the radiator and the reflector, wherein the reflector is configured to direct radiation emitted from the radiator such that reflected radiation is characterized by an emission pattern. 13. The device of claim 12, wherein the antenna is configured to receive radiation from a region defined by the emission pattern. 14. The device of claim 11, wherein the antenna is configured to transmit signals to one or more airborne radio stations. 15. The device of claim 11, wherein the antenna extends vertically from a top surface of the floating base, and wherein the weight counterbalances a weight of the vertically extended antenna. 16. A method comprising: providing a liquid to a vessel such that the liquid does not fill the vessel;coupling a radiator to a reflector such that there is a separation distance between the radiator and the reflector, wherein the radiator is configured to emit radiation according to a feed signal, and wherein the reflector is configured to direct radiation emitted from the radiator such that reflected radiation is characterized by an emission pattern;coupling a first side of a floating base to the reflector, wherein the floating base is comprised of a first material that is positively buoyant in the liquid;coupling a second side of the floating base to a weight, wherein the second side is substantially planar, and wherein the weight is comprised of a second material that is negatively buoyant in the liquid;positioning the floating base on the liquid inside of the vessel; andsealing the vessel to prevent the liquid from escaping the vessel. 17. The method of claim 16, wherein the reflector is substantially parallel to a surface of the liquid such that the emission pattern is substantially perpendicular to a surface of the liquid. 18. The method of claim 16, wherein the floating base is configured to position the reflector at a non-zero angle with respect to the liquid such that radiation is emitted from the radiator at the non-zero angle with respect to plumb.
