Description:
Listening to global radio broadcasts is a wish for every radio enthusiast. However, with the development of society and the increase of modern equipment in cities, electromagnetic interference has also followed, making it an extravagant hope for everyone to listen to short-wave wireless radio in cities. Inverters, neon lights, LED screens, electronic ballasts, etc. are all strong sources of interference. Therefore, we promote this active small loop antenna. With small size, it can be placed in your balcony. Of course, it is better to install it on the outside of the balcony, the effect of which is better.
This antenna has a certain directivity. The direction of maximum signal reception is in the direction of the vertical axis of the ring, and the direction of maximum suppression is horizontal on the plane of the small ring. Using this feature, we can suppress surrounding interference signals by adjusting the direction to achieve a better SNR. A low-noise amplifier is installed at the bottom of the small ring to amplify the small signal and input it to your radio through a coaxial cable. In order to simplify the circuit, coaxial power supply mode is adopted. The power adapter of this product can be automatically adapted directly from 100-240V, which solves users' troubles.
This antenna can receive frequencies such as medium wave and short wave. It covers frequency 100KHz-30MHz. There is an adjustable potentiometer inside the amplifier box under the small ring, which is not necessary for general users to adjust. It has been adjusted to the appropriate level by manufacturers. If it is needed, users can adjust by themselves. Adjust the radio, radio station, or SDR receiver to a desired frequency, and then turn the antenna direction to the maximum noise, adjust the potentiometer until the background noise is greater, then the adjustment can be completed.
Made of 304 stainless steel spring steel wire, antenna vibrator is not easy to rust or corrode after long-term outdoor use. The amplifier box under the small ring has been waterproofed for long-term outdoor use.
Installation Method:
It can be hung outside your balcony. It is best to use a PVC pipe or bamboo pole or wooden pole, as far as possible to maintain a round shape.
