Antenna Diplexer ZA-F10 VHF + UHF (box-mounted PCB)

View of the diplexer in VHF antenn box.

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

For reception of broadcasts from distant and/or low-power transmitters we recommend to employ Terra HS-013 R82010 or Alcad CA-215 R90461 amplifier with independent gain control in VHF and UHF bands.
