View of the antenna

Antenna suitable for DVB-T/T2 signal reception
The Tri Digit ECO A2665 37-element antenna for the whole UHF band (ch. 21-60) equipped with LNA-177 B4009 amplifier (max 30 dB) is a cheaper version of the popular A2675 model, with nearly identical parameters. Due to special design of the array, the antenna has a very high gain, despite its compact size. The amplifier allows reception of broadcasts from remote transmitters, located even 50 km away. The receiving elements are made of aluminum, except for the reflector, made of galvanized steel.
The Tri Digit A2665 antenna is sold in the form nearly ready to use (assembled in 90%), in individual packaging (cardboard box) containing instruction leaflet.
There is a version of the antenna without an amplifier - A2660.
