VAMP9234 active whip antenna (9k-30M)

The active whip antenna VAMP 9243 consists of a vertically placed whip rod and an impedance matching amplifier. The standard length of the whip rod is 1 meter. In the frequency range of 9kHz-30MHz, the conversion factor (antenna factor) is a constant value (10dB), independent of frequency. If you need to measure very strong field strength, you can add a 20dB attenuator option.

main feature:

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

The pole 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.
