The antenna holder/balun VHBA 9123 with low loss transmission line transformer are primarily designed for the use with biconical elements such as BBA 9106 or BBAL 9136. It may also be used with rod elements as a dipole with improved bandwidth or collapsible biconical elements like FBAB 9177 or FBAL 9178.

The VHBA 9123 represents a binding link between the high symmetrical antenna holder VHA 9103, VHBB 9124 and the high power antenna holder VHBC 9133 and VHBD 9134. The VHBA 9123 4:1 balun provides an optimized solution for immunity testing and the measurement of shielding effectiveness. Especially at low frequencies, the power requirement is dramatically reduced thanks to the nearly lossless 4:1 balun. Biconical antennas are generally mismatched at low frequencies and show a negative gain.

Typical Application:

  •  Immunity testing up to 100 W
  •  Shielding effectiveness measurements
