: Start with slightly longer wire lengths to allow for trimming.
: Its low angle of radiation makes it superior to a standard half-size dipole or G5RV for long-distance contacts. download the g7fek antenna construction guide
: The G7FEK design relies heavily on a solid RF earth or counterpoise. Connect the coax shield to at least one 65ft insulated wire laid on or just above the ground. Tuning for Optimal Performance : Start with slightly longer wire lengths to
: Use 450-ohm ladder line or two parallel wires spaced at least 20mm apart. Short both conductors together at the top and bottom. Connect the coax shield to at least one
: Connect the center conductor of a 50-ohm coaxial cable to the shorted bottom of the vertical section.
: It naturally resonates on multiple HF bands by utilizing odd harmonic resonances. 80m Antenna for small gardens | G7FEK Amateur Radio
: Use a non-conductive fiberglass mast for support. If using a metal pole, ensure the vertical element is spaced at least 1–2 feet away to prevent detuning. Key Benefits of the G7FEK Design
