JYR8010-150W End Fed Half Wave Antenna for Ham Radio 8 Band 10m 12m 15m 17m 2
Since its launch, this antenna has been highly praised for its sufficient power and high efficiency. The radiator is made from 2.5 square millimeter thin-skinned wire, and in March 2022, the parameters of the balun were optimized to achieve lower insertion loss and standing wave ratio, bringing the impedance closer to 50 ohms. End-fed antennas are characterized by their multi-directional properties, eliminating the need to choose a specific direction during setup. It is advisable to select an open and elevated location. When setting up the antenna, it should be position meters away from any objects it should be positioned more than 3 meters away from any objects (including tree leaves), and if there are metal objects, it should be placed more than 5 meters away.
If the setup environment affects the resonant frequency, you can adjust the structure by slightly modifying the length of the fold-back at the end; however, trimming is not recommended. The balun has a radiator on one side and is empty on the other. This structure makes the antenna very convenient to set up; simply pull both ends with a rope, ensuring that the radiator and balun are more than 3 meters away from any objects. It can be horizontally, vertically, or diagonally pulled, and the balun can be placed either above or below, making it suitable for concealed setups, especially ideal for rapid deployment in urban areas and the wilderness.
