Use of Panel Antennas with Reduced Reflectors and Slant Polarization at VHF Broadcast Sites

The possibility of using panel antennas with slant polarization to ensure uniformity of the circular radiation pattern when placing digital radio broadcasting antennas of DRM+ standard and analogue FM radio broadcasting on towers with a large (12 meters) cross-section is considered. The calculations showed the possibility of achieving a positive effect, as well as the possibility of using smaller reflectors and forming a sectoral radiation pattern. The possibility of using the considered solutions for towers with a standard cross-section of 1.75 m x 1.75 m, 2.5 m x 2.5 m is also shown. The use of slant panels with a reduced reflector as an alternative option for obtaining a radiation pattern unevenness acceptable for radio broadcasting is advisable in the case when mixed polarization is not a significant limitation for the broadcaster.
