Ku band- RX Antenna & Downconverter
Antenna Project Description
The “DW0146_103” is an active antenna developed under a programme of and funded by the European Space Agency (ASTREA project). It provides great signal because has typically 20dBi gain followed by an active amplifier stage providing around 25dB additional gain. The topology selected is a Sot Coupled Antenna (SCA) and is natively designed with horizontal polarization.
