TV single- channel (I-II ranges) TV and radio broadcasting (66-74 MHz., 100-108 MHz) broadcasting antenna of panel type.

PURPOSE AND STRUCTURE

Antennas are used for TV broadcasting at one TVC at I and II ranges and radio broadcasting at 66-74 MHz ranges, 100-108 MHz. Antenna panels are installed on faces (Pic. 1 –horizontal polarization ) or on the bands (Pic. 2- vertical polarization) of standard bearings in cross-sections 1,75×1,75m,2,5×2,5m… When there is lack of free space at the bearing for installation of antenna with vertical polarization , it can be combined with panel antennas of III range on the bearing (Pic. 3). In this case decoupling among antennas is run up to not less than 30 dB.

See overall dimensions, weight of the panel in the table.

Antenna panel consists of the shield (steel) and half-wave vibrator (brass).

Elements of metalware used for installation of antenna to the bearing are part of the delivery set. The enterprise performs affixment of the antennas to the bearing.
