137MHZ Quadrifilar Antenna for WEFAX

My satellite antenna (september 2007, KN45CE)

The Quadrifilar antenna is one of the best types of antennas for use in receiving polar-orbiting weather satellites.
This is the type of antenna that is actually used on the satellites themselves for transmitting the images.

NOAA-17 Antenna

Attention to polarization sense!!!
Use first image for detailes. If "coil" direction is opposite, the received signal will be almost zero.
