WebJan 24, 2024 · As long as it remains a half wavelength long, the gain and radiation pattern of the antenna is the same even if we feed this half wave wire at various points along its length. At nearly every point that we choose to feed it, the antenna will not be resonant - that is to say at nearly every feedpoint, there will be reactance. WebI'm using a 37.5cm Nagoya NA-771, which is the quarter wavelength of absolutely none of the two frequency ranges above. While learning on this topic, it seems antennas with a quarter wavelength size are more effective. Quarter wavelength antenna size for : 430Mhz : ~17cm. 150Mhz : ~50cm. So there's a big difference here.
