B105 antenna - GNSS professional level antenna for receiving navigation signals in the range L1 (GLONASS, GPS, GALILEO, SBAS) and is designed for use on mobile objects in harsh environments for industrial, agricultural and special applications.
Antenna receives the signals with the right-hand circularly polarization and suppresses signals with the left-hand circularly polarization. Antenna provide a reduction of multipath effects. |

Design features
The antenna comprises an amplifier with low noise and a SAW filter to protect the interference from GSM.
Emitter antenna receives signals with right hand circular polarization and weakens the multipath effects.
Antenna amplifier is protected from damage by input power up to 1 watt.
Antenna housing is made of aluminum alloy, radome – made of impact resistant plastic, cast.
The antenna mount is magnetic and (or) screws.
B105 antenna (04, 05, 07, 08) - embodiment of the antenna without housing, for incorporation into the housing of the consumer navigation equipment.
