main feature:

       The VHA9103 half-wave tuned dipole antenna, with a maximum effective transmission power of 10 watts, is used for field strength testing and reference for generating preset VHF electromagnetic fields.

       You may be used BBA 9106 BBAL 9136 or the like or biconical element FBAL 9178 or like foldable FBAB 9177 biconical element, instead of two sets of telescoping elements. Due to the tapered element (ordered separately), the 1:1 balun/cage can be used as a broadband antenna without adjusting the extension length according to the frequency.

       VHA 9103 is mainly used in the emission test of EMC test. A high degree of symmetry, accurate calibration data, excellent workmanship and low loss make VHA 9103 the dominant balun in the antenna market.

       For the generation of high field strength, we recommend using 4:1 baluns/brackets VHBA 9123 (50w), VHBC 9133 (1kw), VHBD 9134 (2.4kw) or VHBD 9134-4 (4kw), which provide superior efficiency And rated power, especially in the low frequency range.

       Use precision dipole antennas VHAP and UHAP to evaluate the performance of the test field (field normalized attenuation).

       The antenna bracket is a 475 mm tube with a diameter of 22 mm, with an index ring. The component can be fixed in position on a vertical or horizontal plane with 3 mm screws. When inserted into the removable mast system AM 9104 movable antenna holding box Middle time. The height of the antenna ranges from 0.4 meters to 4 meters.

       At the back of the VHA 9103, a high-quality N-female connector provides contact with the 10-meter long coaxial antenna cable AK 9513. Record the cable loss to correct the field strength or erp calculation.

       Half-wave tuned dipole antenna UHA 9105 can be used as an extension of VHA in the high-end frequency range (300-1000 MHz).
