FIELD: radio engineering and communications.
SUBSTANCE: invention relates to radio engineering and can be used in antenna-feeder devices as isotropic in the horizontal plane of the antenna, when working with horizontal polarization, in transport, mobile and fixed radio communication systems, television and radio navigation. Proposed combined ship TV antenna can also be used as a fastening device for the installation of other antennas. It has increased mechanical reliability and simplified design, simplified electrical power supply and the possibility of combining with additional antenna devices of ship radio systems of river and sea radio frequency bands with deep polarization and inductive isolation.
EFFECT: technical solution of the TV antenna is adapted for installation in cramped conditions on small vessels, while providing a television reception with a simultaneous co-enhanced device for accommodating predominantly whip antenna VHF antennas.
