| |
 |
MarAnt+ is an active low profile GPS/GLONASS antenna. It is available in GD (GPS L1/L2) or GGD (GPS/GLONASS L1/L2) versions.
MarAnt+ was specifically designed as a rover antenna for land and marine applications. It has highly waterproof housing. Wide antenna pattern provides satellites tracking up to zero degrees elevation. Integrated low-noise amplifier provides low-noise operation within frequency bands 1565-1615 MHz (L1) and 1217-1265 MHz (L2). LNA has excellent filters for out-of-band rejection. Also LNA has fast clamping diodes in both L1 and L2 channels to prevent the device of being destroyed by high-voltage in-band jamming. DC power supply is supplied through the coaxial connector.
Antenna boards are made of temperature-stabilized ceramic.
MarAnt+ may have an optional cone environmental cover. |
