VE7CA 6m antennas
Portable 6-meter quad and Yagi antenna designs with construction details and performance measurements.
Description
The ARRL ANTENNA Vol 5 COMPENDIUM features an article detailing two portable 6-meter antennas: a 2-element quad and a 3-element Yagi with telescoping elements. The 2-element quad exhibits a measured gain of 4.2 dB over a dipole, while the 3-element Yagi achieves 5.8 dB over a dipole. Both designs prioritize ease of construction and rapid assembly/disassembly for portable operations.
Specific dimensions are provided for a 3-element 6-meter quad using #14 bare copper wire. The reflector element diameter is 6.2958 meters, the driven element 6.125 meters, and the director 5.8547 meters. Element spacing is 0.9398 meters between reflector and driven, and 1.1684 meters between driven and director. The SWR is under 1.26:1 from 50 to 50.4 MHz, with a feed point impedance of 48.75 -j0.13 Ohms at 50.2 MHz, suitable for direct 50 Ohm coax feeding with a current balun.
