This antenna can be used regardless of whether the radio is equipped with an external antenna jack. For the radio without an external antenna jack, the antenna is equipped with two small clips, one to clamp the whip antenna, and the other to clamp the ground terminal of the radio.(The negative pole of the battery compartment). For a radio with an external antenna jack, it can be used directly by plugging in the antenna.
The included magnet is used by the radio when listening to medium wave broadcasts. How to use: Connect the output signal to the magnetic rod, then parallel the magnetic rod with the built-in magnetic rod antenna of the radio, and adjust the controller knob to maximize the signal output

This antenna is suitable for most radios. This antenna is an active antenna. It is not suitable for use in strong signal areas. It has a certain amplification effect on weak signals, but it is not suitable for use in every place. Please consider carefully when purchasing. I just bought it, thank you for your cooperation!
Buyers need to know: Please carefully understand the following content before buying, thank you for your cooperation! Buyers who do not know how to operate are not recommended to buy. If you need more information about the antenna, please check it on the broadcast fan website! This antenna is suitable for radio enthusiasts with strong hands-on ability to buy!
Degen DE31MS medium wave/short wave active antenna related principle and performance introduction (English description jam)

Degen DE31MS short-wave active receiving antenna is a ring resonant amplified antenna, so it has the characteristics of high anti-interference, high sensitivity, high selectivity, compactness and ease of use.
2. DEGEN DE31MSAnti-interference
Loop antennas have obvious directivity by nature, which provides extremely favorable conditions for anti-interference. Only by aligning the weakest receiving direction of the antenna to the interference, the interference can be reduced or even eliminated.
Environmental interference is mainly electric field interference, while loop antennas happen to be magnetic field antennas, which are obviously superior to electric field-type wires such as whip antennas and long-wire antennas.
3. DEGEN DE31MSHigh sensitivity and high selectivity
DE31MSThe antenna is equipped with a low-noise amplifier of the field effect tube, which is a guarantee of high sensitivity; the antenna loop and the varactor diode constitute a highQThe value of the resonant circuit is equivalent to adding a tuning high amplifier to the radio, which greatly increases the selectivity.
4.The entire antenna accessory is placed indoors, compact and easy to use.
