Claim 0:
1. An antenna system comprising at least one vertical take-off and landing (VTOL) unmanned aerial system (UAS) with an embedded flight control system for UAS flight control, the VTOL UAS, in use, being powered via a coaxial tether by a DC circuit coupled with a RF transmitter to simultaneously power the UAS and radiate a desired pattern of RF energy from the tether, the tether thereby acting as an antenna of said antenna system when the VTOL UAS is, in use, airborne; wherein the coaxial tether comprises a core conductor and an outer sheath conductor; wherein the DC circuit is coupled to the outer sheath conductor and to the core conductor to apply DC energy between the outer sheath conductor and the core conductor and wherein the RF energy from the RF transmitter is applied to the outer sheath conductor.
