Although broadband antennas are used for day-to-day EMC measurements, especially when swept techniques are used, there are a number of applications when a fixed frequency half-wave dipole can give an improved performance. It is preferable, and in some cases required, to make site attenuation measurements using dipoles. The VDA 6116A covers the frequency range 30 - 300MHz and has an identical balun to the VBA 6106A broad-band biconical antenna. The UHA 9105 dipole covers the frequency range 300MHz - 1GHz. These antennas are mechanically compatible with most Schaffner EMC mast and tripod systems.
