    • Commodity name: VAMP9234 Active Rod Antenna (9k-30M)
    • Commodity ID: 1064753210574131200
    • 品牌11: SCHWARZBECK
    • 描述: The active tie rod antenna VAMP 9243 consists of a vertically placed tie rod and an impedance matching amplifier.
    • 品牌: SCHWARZBECK

           The active rod antenna VAMP 9243 consists of a vertically placed rod and an impedance matching amplifier. The standard length of the rod is 1 meter. In the frequency range of 9kHz-30MHz, the conversion factor (antenna factor) is a constant value (10dB), which has nothing to do with frequency. If you need to measure very strong field strength, you can add a 20dB attenuator option.

  • main feature:

          The active rod antenna VAMP 9243 consists of a vertically placed rod and an impedance matching amplifier. The standard length of the rod is 1 meter. In the frequency range of 9kHz-30MHz, the conversion factor (antenna factor) is a constant value (10dB), which has nothing to do with frequency. If you need to measure very strong field strength, you can add a 20dB attenuator option.

           In order to reduce the influence of the power supply on the measurement, VAMP 9243 has a built-in NiMH rechargeable battery, which can work for up to 50 hours. Charging time is 2-4 hours with a fast charger.

           The rod antenna and amplifier housing are made of aluminum. The top plate can be fixed to the metal ground plane with 4 screws. Connectors and controls are located under the top plate. The length of the rod starts exactly from the top plate.
