Webend-fed wire, along with more directional arrays such as the terminated long-wire, the terminated V-beam, and the rhombic. The theory of long-wire antennas appears early on in most college antenna texts. the obligatory collection of basic equations that describe some long-wire properties, most authors pass on, WebYes, on frequencies close to the wire's resonant frequency, main lobes will be perpendicular to the wire. However, Keep in mind that as frequency increases the lobes will more and …

WebThe EFHW antenna is one of amateur radio’s oldest antenna designs. EFHW stands for “End Fed Half wave” and was first introduced way back in 1927 by the Austrian radio amateur, Dr. Josef Fuchs, OE1JF. Later the antenna got name “Fuchs Antenna.” It was patented in 1928, published in QST magazine and subsequently forgotten for many years.
