Description

The lightweight antenna VBA 6106A offers a compact solution to measurements in the frequency range 30 to 300 MHz. It is ideal for open site measurements or applications in anechoic chambers where space is at a premium. The VBA 6106A has a coaxial wound balun and can be used to transmit signals. The maximum continuous input power is 10 Watts.

Above approximately 70 MHz the antenna factor is similar to that of a tuned half wave dipole but allows measurements to be made without the need to adjust the antenna at each frequency. Below 70 MHz the antenna factor is higher than that of a tuned half wave dipole but is adequate for many purposes and is much smaller.

At frequencies near 30 MHz, the adjustable half wave dipole elements ‘droop’, and may overhang the ground plane of an open air test site, when horizontally polarized.

Both these effects can cause significant errors and measurement repeatability problems. The smaller, rigid construction of the VBA 6106A overcomes these problems. Biconical antennas are preferred in the range 30 MHz to 250 MHz by CISPR 16-1-4 in order to achieve a low measurement uncertainty.
