HD-330 Vehicle Shortwave Antenna 3.5-50MHz Electric Control Screwdriver Antenna

HD-330 Portable 3.5-50MHz Vehicle Shortwave Antenna Multi-band Electric Control Screwdriver Antenna Features: - It is a multi band shortwave antenna, which is designed specifically for amateur radio. 3.5-50MHz, suitable for shortwave radio stations. Quick tuning, using electric tuning method. Portable design for easy installation and installation.

Description: - It can resonate with the working frequency of the radio by adjusting the height of the inductance coil. For 3.5MHZ frequency band, it takes up to 50 seconds to adjust the scale to the highest position; For 5-50 frequency band, it can take up to 20 seconds to adjust the scale to the corresponding position. Synergistic effect: It is possible to simultaneously use the built-in tuning of the radio station (which requires radio support) for tuning to achieve better standing wave ratio. This antenna is powered by a car cigarette lighter interface, and the top is a portable design with a lever antenna. Use a controller to adjust the frequency scale on the inductance coil to obtain the ideal standing wave ratio. The design with a power resistance of 200W (SSB) can meet the needs of most amateur shortwave radio stations. Specification: - Model: HD-330 - Frequency range: 3.5 - 50MHz (only amateur frequency band) - Length: about 0.7 - 2.9m - SWR. Usually it costs about 30USD-50USD. If you receive the item that not satisfied or defective, please do not open case and kindly notify us within 30 days.
