Quadrifilar helicoidal antenna - Photos
Detailed view of the balun J-J used RG-400, too rigid to bend and pass through the tubing
Quadrifilar Antenna to receive 137 MGHz
Creation of a four-wire antenna to receive the 137 MHz signal from NOAA meteorological satellites
Swiss quad for 144Mhz
This antenna can be made for 50 or 28 MHz. The length of the elements is given at the bottom of the description
The 2 Element HB9CV Beam
The Beam is a coax-fed version of the ZL-Special. The reflector is fed 225 out of phase
