The long wave, medium wave, and short wave are all balanced, amplified, and squelched. It is your ideal DX device! Frequency coverage: 50kHz-30MHz OIP2: 90dBm+ OIP3: 48dBm+ Compared with ordinary whip whip, it has better anti-interference and omni-directionality, effectively resists electromagnetic interference and power noise, and performs better in harsh electromagnetic environments. With aluminum alloy shell and circuit glue protection, it can better adapt to the outdoor environment.
Exclusive custom copper ring 2. Its amplifier unit is equipped with an m connector, which is more convenient for carrying and outdoor erection 4. Exclusive design tuning and tuning-free band switch 5. Can be used indoors and outdoors, with strong anti-interference ability 6.

Instructions: There are two knobs on 1530 outdoor controller (antenna side). The top knob is for high and low bands.
It is measured on three levels, respectively 40-50-60. The frequency range of 40: 3-10MHz. 50's frequency range: 10MHz-30MHz. When in these two levels: first adjust the lower knob to 0.Then turn the knob slowly to the right again. Once when the clearest sound or the loudest noise is heard, it means that the device has reached the best chirp point. Then adjust the direction and erection position of the small ring. It is recommended to install the antenna on the balcony or outdoors. The knob on the indoor controller is to reduce noise: when the value is 100, it has the smallest gain and the lowest noise.
When the value is 0, the signal is the strongest. Generally it is adjusted to 50. When the top knob on the outdoor controller is 60: it is for tuning-free. When the 60 gear is turned on, the lower knob does not work. At this point, you only need to adjust the direction of the small ring.
