Details
The antenna supports reception of the digital DVB-T/T2 standard.
The DIPOL 28/5-12/21-48 A2850 professional DVB-T/T2 antenna set has been designed for reception of TV broadcasts in VHF (174-230 MHz) and UHF (470-694 MHz) bands. Thanks to a universal construction, the VHF and UHF antenna segments can be set to the vertical (V) or horizontal (H) polarization of the received signals.
The antenna features high gain, which will allow you to receive signals from a distant TV transmitter. The A2850 professional antenna set has a built-in diplexer in the VHF antenna box and an LNA-169 B4008 amplifier in the UHF antenna box. The amplifier used in the A2850 antenna only works on the UHF band. The antenna is pre-assembled. Assembly consists of tightening a dozen screws and takes a few minutes. The main elements of the antenna are made of aluminium, the steel structural elements are galvanised.
The set includes the LNA169-5G B4008 amplifier and 12 V/100 mA power supply
Key features
- antenna set designed for receiving DVB-T/T2 signals from one direction
- in 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
- UHF antenna with LNA-169 B4008 amplifier (powered with 12 VDC from the power supply or with 5 VDC from the input of an DVB-T receiver/tuner)
- pre-assembled
- made of aluminum
- directors and reflectors of UHF band are made of open aluminium section
- modern design - high gain despite a relatively small size
- made in Poland
- packed in cardboard box
Since May 7, 2024, the LNA169-5G B4008 amplifier (previous version LNA-101) is installed in the UHF antenna box, which can be powered by a standard 12 V voltage.
