WebIn the case of a 1:9 UnUn, the power line (coax) impedance of 50 ohm will be transformed up to an impedance of 450 Ohm. After all 50 x 9 = 450. This means that the length of the long-wire antenna must be chosen in such a way that the impedance in the feeding point on as many frequency bands as possible is about 450 ohm. WebThe representation of the source of the electromagnetic fields for a thin‐walled tubular transmitting antenna is examined. Application of a standard formula for the electromagnetic field leads to the concept of a magnetic current source. With this type of source, the correct integral equation for the tubular antenna is easily derived because the standard vector …

WebAug 11, 2024 · A type of coaxial cable that has a tubular outer conductor surrounds the center conductor coaxially and the insulating material is air. ... A 50-ohm coax is connected to a 73-ohm antenna. The SWR is . A. 0.685 . B. 1 . C. 1.46 . D. 2.92 . View Answer: ... A pulse is transmitted down a cable that has a velocity of propagation of 0.8c. Webthe antenna was constant. The converse problem, that of the capacitance of a thick tubular monopole, was solved by Casey and Bansal [13]. Through modification of the per-unit laigth capacitance of a coplanar stripline given by Hanna [14], Casey and Bansal obtained an expression for the equivalait tubular monopole in terms of elliptic integrals. fish oil and aspirin combination
