Band air band receiving antenna MA-AIR 120/300MHz

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

Are there any antennas that are easy to install? A magnet-integrated antenna with a 5m cable mounted and a housing with a total length of only 62cm will greatly enhance the Air Band reception experience. This is a small magnetic antenna that can be installed anywhere - on top of a car, on a balcony, or on a boat. (Because it is a magnet, an iron base is required) Also, since it uses the popular replaceable connector terminal type, an SMA connector is included, but it is also compatible with the antenna terminals of various receivers as an option (see the instruction manual).A scratch-prevention transparent magnet bottom sticker is also included to prevent scratches on your precious car.
