QFH Self Phasing Receiving Antenna


Self-Phasing Quadrifilar Helix

Satellite image data is received with this antenna.
The support structure is made of plastic pipe. 
Helical elements are loops of LMR-400 coaxial cable. 
RG-8 Mini-Foam coax is used for the balun and feedline.
Dimensions are from John Coppens' Antenna Calculator.
Height is 4 meters above ground at the top.
