Description

DAT BOSS LR 47dB gain antenna for receiving DTT signal over long distances.

What are the main features of the Televes DAT BOSS LR 149721 antenna?
High dynamic range: it allows the reception of high-quality TV in a variety of critical situations, from areas where signals are very weak to installations with high signal levels
Expanded DTT coverage area: up to 27% higher than previous models
More stable signal reception: it supports signal variations or fading with no effect on the TV installation
Optimal C/N: thanks to a noise figure of only 1.2dB that enhances the received signal quality
Very high gain: TForce technology provides BOSS with an increase in gain of up to 13dB
The DAT design, based on 3 Yagi antennas with asymmetric directors, provides great directivity as well as an optimal anti-echo radiation pattern
Special double-U dipole: it’s open/close format provides optimal frequency response flatness
A fully shielded switch box protects the BOSS system from impulsive noise; grounded for full protection against electrical discharge
Manufactured in aluminium (stainless) for a long service life
Fully automated manufacturing in Europe under the most stringent quality controls: a synonym of high reliability
Two work mode options: Intelligent low power consumption mode or passive mode (lack of power supply).
