How To Build A QFH Antenna

If you can't see the video, please insert this title URL into your browser search box: If you do a lot of weather satellite monitoring, you'll find this tutorial on QFH antennas (Quadrifilar Helix Antenna) most interesting. You can modify the antenna to cover GPS and Amateur/Ham Radio bands as well. Her are some general comment from the author: If you want to build an antenna to receive signals from a weather satellite, you will need a special kind of circular polarized antenna known as a quadrifilar helix antenna. In this video, we'll go through the theory and practice behind how to build a QFH antenna. These antennas are especially-made for NOAA weather satellite reception and are tuned to 137MHz to receive polar orbiting satellite signals. This is part of Project TIROS for element14 presents.
