Simple Ham Radio Antennas

  If you want to receive photos from weather satellites, you'll need to build a simple Quadrifilar Helix (QFH) antenna.  The QFH antenna is circular polarized antenna designed to receive signals from NOAA weather satellite on a frequency of 137 mHz. In this video, the "Airborne Surfer" explains the theory and practice behind this fascinating antenna.

Here are some comments from the "Airborne Surfer": 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 orbi...
