Getting back on the air researched several wires which would fit my garden, tried a home-brew Carolina Windom and hey presto its a gem on all bands but Top Band. It is an antenna system including a radiating element and a length of transmission line designed to present a "correct" impedance at a design frequency. It can be used with a tuner on different bands, however it will not be very efficient. The ZS6BKW antenna evolved from an optimization of the G5RV antenna that, in general, sacrifices 75m operation to gain 17m and 10m operation. The losses in the coax will be slightly greater but it will solve the delivery problem. g5rv et zs6bkw Il faut rappeler que la G5RV est à l'origine une antenne monobande (sur 14 MHz); suivant l'environnement elle peut avoir d'autres résonances, et si on lui met une boîte d'accord elle devient multibande, comme la Lévy.

Side by side comparison of two ham antennas. only has a real interesting pattern at 20 meters, where it is an extended double zepp with a special open wire section to give a decent match at 50 ohms. The same is true of 10 meters; as frequency goes up, multibanding gets more quirky, and SWR curves and efficiency suffer. Perhaps too many new hams embarking on their first HF adventures think only of resonant dipoles fed with coaxial cable and plugged directly into the transceiver's output connector. Fed by ¼ λladder line into a balanced tuner. A regular-sized G5RV is designed for 20m and also works well on 40m & 80m. The G5RV, after all, was pretty much designed as a 20 meter antenna.

Characteristics Note: The above values are initial values. It is a good thing for a voltage input, as if the input impedance is high compared to the source impedance then the voltage level will not drop too much due to the divider effect. 95 - Phased Loop Antenna. The G5RV antenna is a type of dipole antenna, and it can be acquired for a very small cost from many ham radio retailers. Double-coax-wound traps have two parallel windings of coax cable (A and B) rather than a single-cable winding. Switched over to the DOUBLE BAZOOKA and started listening to a QSO in progress. 22 Double Windom for 9 Bands. 83 one side.

If the attic area is not large enough to accommodate an almost full-size dipole, simply erect as much of the antenna as possible in a straight line, then bend the ends of the dipole up, down, or sideways from the main portion of the system. 5m (44 ft) version would be an extended double zepp for 10m metres (28 MHz). 64 mm = 14 AWG. It works decent for what it is. Superimposed is the pattern of a 20 meter dipole at the same height. This is a great question, as the coax you select can make a dramatic difference on the performance and range of your antenna system. Louis Varney (G5RV) invented this antenna in 1946. The stacked cores double the choking and isolation while retaining the perhaps something more akin to the the so called "Carolina Windom," or G5RV, both of.
