ZAMETTER End-fed Half-Wave Antenna Professional Amateur Radio Half Wave Antenna 8 Band Long Wire Antenna 150W SSB Power Handling 10-80m Bands Multi-Band Half Wave Antennas Kit(4010-150W)

Features: * Wide frequency range: This half-wave antenna supports multiple frequency bands (10m, 12m, 15m, 17m, 20m, 30m, 40m, 80m), provides excellent performance at different frequencies, and provides unparalleled flexibility for various radio applications. * Power handling: Professional end-fed antenna, single sideband (SSB) power handling is less than 150W, continuous wave (CW), FT8 power handling is less than 100W, which can meet your different usage needs. * Easy to hang: The distance between the antenna and objects (including leaves) is 3 meters (9.8 feet) and the distance from metal is 5 meters (16.4 feet). It can be hung horizontally, vertically or diagonally - the balancer can be placed in a flexible way. It is for ideal for field operations, home or backyard use. It is your for ideal choice for long-term field deployment, long-term camping and home environments such as overload. Perfect for POTA and Connecting the World * For Durable Construction: The 1:64 balun antenna features an ABS housing, which is for durable and has exquisite craftsmanship, long-lasting and reliable operation under various conditions. * Our end-fed antenna is newly designed by . It adopts an a-ir convection cooling housing, with cold a-ir entering from the bottom and hot a-ir exhausting from the top, effectively cooling the end-fed antenna naturally to prevent overheating. This allows the antenna to operate stably for longer and receive more radio signals. * The distance to any obstacles (including walls, trees, leaves, non-metallic objects) must be greater than 3 meters throughout the length of the antenna. If you encounter metal objects (such as wires, windows, metal railings), keep a distance of more than 5 meters from these obstacles for optimal performance. The antenna height should be as high as possible. It can be pulled horizontally, vertically or diagonally. The provided pull rope has an estimated service life of 5 years, but it is recommended to be checked every 6 months. If any abnormality is found, please replace the pull rope immediately. * Due to the use of a high-impedance transformer, this antenna generates a lot of heat. When the ambient temperature is below 18℃, it can be used at nominal power. If the ambient temperature exceeds 18℃ and the standing wave ratio increases during use, the transmission power should be reduced.

However, if modes such as FT8 or FT4 are used and interference with other devices occurs, an external grounding system for the antenna can be used. The specific is as follows: connect a 1-2 meter long single wire at the transformer connection point and let it hang naturally without grounding. However, adding a grounding system will cause the resonance point to shift, and the unit length needs to be adjusted using an antenna analyzer. If necessary, shortening the grounding system may help reduce the resonance point shift and achieve a balanced effect. Package Contents: 1 x end-fed half-wave antenna kit
