TV double-oscillating (II-III ranges) TV and radio broadcasting (66-74 MHz, 87,5-100 MHz) transmitting antenna of panel type

PURPOSE AND STRUCTRE

Antennas are used for TV broadcasting at II and III ranges and radio broadcasting at 66-108 MHz or 87,5-108 MHz. Aerial panels are installed on the faces of standard bearings in cross-sections 1,75×1,75m or 2,5×2,5m (Pic. 1 –horizontal polarization and pic. 2- Vertical polarization). See overall dimensions, weight of the panel of indicated ranges in the table.

Antenna panel consists of a shield (stele) and two half-wave vibrators (brass).

Metalware elements for installation of antenna to the bearing are part of the delivery. The enterprise performs “affixment” of the antennas to the bearing.
