JYR4010-60W 4-Band End Fed Antenna Low-Power Shortwave Antenna not Requiring Antenna Tuner

Description:
The antenna is designed for HAM using QRP, featuring small size, light weight and portable design. It adopts the magnetic ring (38x19x13mm/1.5 x 0.7 x 0.5") produced by the world famous factory. In March, the parameters of the balun were optimized, so that the insertion loss and standing wave are lower, and the impedance is closer to 50Ω. Because of its high efficiency, natural resonance does not need to use an antenna tuner.

A single-ended-fed antenna is called an end-fed antenna. Balun has antenna element on one side and without element on the other side. The antenna with this structure is very convenient for erection. As long as the two sides are pulled with a rope, the element and the balun need to be pulled together. It is enough to be more than 3m/9.8ft away from all objects. It can be pulled horizontally, vertically, diagonally, and the balun can be up and down. It can be erected concealed, and it is especially suitable for rapid erection in cities and in the wild.

Specifications:
- Antenna configuration: 20m/65.6ft tinned wire (1.5 square), 20m/65.6ft rope, and 1:64 balun
- Bands used: 28MHz～29.700MHz, 21MHz～21.450MHz, 14MHz～14.350MHz, and 7MHz～7.3MHz
- Power withstand: < 60W for SSB; < 40W for CW; < 30W for FT8
- Gain: (By comparison method) the gain of 28MHz～29.700MHz, 21MHz～21.450 MHz, and 14MHz～14.350MHz exceed that of positive-V and inverted-V antennas of induction type. The gain at 7MHz to 7.3MHz is equivalent to it
