Wide-band TV and radio broadcasting antenna of panel type of VHF band with horizontal polarization

(On the basis of zigzag periodical structures for installation at the collateral lines of standard bearings )

PURPOSE AND STRUCTURE

This antenna is a multileveled system in every level of which there are

two, three or four antenna panels.

An antenna panel consists of zigzag periodical radiating structure, a reflector and a power supply unit, protected by dielectric casing.

Antenna panels are installed on the lateral faces of standard bearings.

Antenna panels, distribution elements (power dividers, distribution feeders) and mounting elements for installation of antenna on the bearing are part of the delivery set.
