Detaily

Professional antenna set with H/V polarization Dipol 28/5-12/21-48 DVB-T/T2 tube
Professional antenna set A2811 to receive DVB-T/T2.
Antenna assembled to receive VHF in horizontal polarization.
Professional antenna set with H/V polarization Dipol 28/5-12/21-48 DVB-T/T2 tube
Professional antenna set A2811 to receive DVB-T/T2.
Antenna assembled to receive VHF in vertical polarization.
Antenna suitable for digital DVB-T/T2 signal reception.
The professional antenna set with H/V polarization Dipol 28/5-12/21-48 DVB-T/T2 A2811 is designed to receive DVB-T/T2 digital terrestrial television in VHF band (174-230 MHz) and UHF band (470-694 MHz). Universal design of the antenna enables the user to freely change polarization of reception V/H for both, the VHF and UHF bands.
The antenna is distinguished by high gain, which allows to receive signals from distant TV transmitters. Professional antenna set A2811 has a built-in diplexer in the VHF antenna box, and a balun in the UHF antenna box. The antenna is pre-assembled. The assembly consists in tightening several screws and takes a few minutes. The main components of the antenna are made of aluminum, steel structural elements are galvanized. In the case of transmitters with lower power and/or further away from the place of reception, it may be necessary to use the Terra HS-013 R82010 or CA-215 R90461 amplifier having independent gain control, separately for VHF and UHF bands.
Key features:
  • the antenna receives DVB-T/T2 TV signals from one direction
    • in the VHF band (channels 5 - 12) in horizontal or vertical polarization
    • in the UHF band (channels 21 - 48) in horizontal or vertical polarization
  • built-in VHF/UHF diplexer
  • pre-assembled
  • made of aluminum
  • all directors and reflectors are made of aluminum tube
  • modern design - high gain with compact dimensions
  • manufactured in Poland
  • cardboard box
