JYR4010-400W 4-Band End Fed Antenna Shortwave Antenna HF Antenna

JYR4010-400W 4-Band End Fed Antenna Shortwave Antenna HF Antenna not Requiring Antenna Tuner Description: The antenna has been praised for its high power and high efficiency. It uses a large magnetic ring (63x38x20mm/2.5x1.5x0.8).

Its element is made of 2.5 square thin-skinned wires, and the parameters of the balun were optimized in March, so that the insertion loss and standing wave are lower, and the impedance is closer to 50 ohms. 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 2.5 square wire, 20m/65.6ft rope, and 1:64 balun - Bands used: 28MHz~29.700MHz; 21MHz~21.450 MHz; 14MHz~14.350MHz; 7MHz~7.3MHz - Withstand power.
