Hisonauto AMLA150 Active Magnetic Loop Antenna HA SDR Short Wave Low Noise

AMLA150 receiving frequency range: 0.1-150Mhz.

MLA30+ receiving frequency range: 0.1-30MHz.

NOTE：Recently, some merchants copied our antenna for sale, please pay attention to distinguish the authenticity. Knowledge is pricele, please choose to buy , thank you.

Why AMLA-150 antenna is better than MLA30?

The MLA30 antenna will have noise near 10MHz and 20MHz, because it uses ordinary power or supply ( has a boost function that will affect the antenna reception)，There is another disadvantage. MLA30 uses a feeder to power the external antenna, which willther affect the receiving effect and reduce the receiving performance.The solution used by AMLA-150 antenna is different from that of MLA30. We use a profeional receiving with excellent reception. Radio enthusiasts are welcome to buy it for evaluation and comparison with other types of antennas.

note :

1. The gain adjustment knob rotates clockwise to increase the gain and counterclockwise to decrease the gain. Too high a gain may cause the receiver to be overloaded (do not adjust too high). Too low a gain may cause unstable abnormalities (do not adjust too low) Adjust to the best gain according to the actual situation to get the best effect. After the gain is set, you do n’t need to screw it often. Generally, turn it clockwise to 70%. For most devices, the gain is appropriate.2. Tighten the erfly nut with proper strength, if it is too tight, the PCB pad will have a deep indentation3. If it is used by radio, in order to avoid overload in DX / e gear, please turn the radio e switch to Local / local (Normal) gear or Normal4. The circuit board can not touch the metal conductive object, it will short circuit and burn the LED lamp, and the broken LED lamp will affect the antenna work5. The antenna has strong directivity, and the direction and elevation angle need to be rotated to obtain the best signal quality.

Guidelines for Welding Parts:

① There is an orange circle on the resistor, it is a 4.7K resistor② There are 3 red circles on the resistor , it is a 2K resistor③ D1 is directional, please note that the circle is on the right④ C1 resistor model is 474

At present, this shortwave active loop antenna with the highest cost performance, you can buy it to test and compare with other antennas. If you are not satisfied with this antenna, please give one star or return it.

Recently there have been customer reviews, signal overload, and the use of faults pay attention to the following points:1. Keep away from strong interference sources such as electric vehicle chargers.2. Use 8.5V or 9V dry batteries or rechargeable batteries, or rechargeable batteries used by 6LR61 6F22.3. When using, make sure that the has enough power, because the battery will affect the receiving effect during charging.4. Put the antenna as close as poible to the window or outdoor, the reception effect is better.5. The gain is adjusted to about 70%, and the receiving effect is the best.6. From the structure of the circuit board, we can see that the purpose of using the least electronic components is to achieve the best receiving effect. The more electronic components, the more interference sources.

Frequently Asked Questions:

1. Is Desheng PL365 applicable? ----------------- Not applicable, do not recognize the interface2. 9V battery input (batteries used by 6LR61 6F22)Is the battery really dead? ----------- If the light doesn't light up, there is no electricity3.
