main feature:

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

Instead of 2 sets of telescoping elements, biconical elements such as BBA 9106 or BBAL 9136 or collapsible biconical elements such as FBAL 9178 or FBAB 9177 can be used . Thanks to the tapered elements (ordered separately), the 1:1 balun/cage can be used as a broadband antenna without frequency-dependent adjustment of the extension length.

VHA 9103 is mainly used in the emission test of EMC test. High symmetry, precise calibration data, excellent workmanship and low loss make VHA 9103 the leading balun in the antenna market.

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

The performance of the test field (site normalized attenuation) can be evaluated using sophisticated dipole antennas VHAP and UHAP .

Antenna support is a 22mm diameter 475mm tube with an indexing ring, the element can be fixed in position with 3mm screws in a vertical or horizontal plane, when inserted into the removable mast system AM 9104 removable antenna holding box Middle time. Antenna heights from 0.4m to 4m.

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

The half-wave tuned dipole antenna UHA 9105 is available as an extension of the VHA in the high frequency range (300-1000 MHz).
