Product Details

The A.H. Systems SAS-540 Biconical antenna operates efficiently over the frequency range of 20 MHz to 330 MHz and is designed within the MIL-STD-462 size requirements. Compact in size, this Biconical Antenna is an ideal for use in a shielded room or anechoic chamber. The antenna balun is designed using as unbalanced to balanced transformer for improved linearity response and is the standard workhorse of any EMC compliance test house. CISPR 16-1-4 specifies the Biconical antenna as the preferred antenna to cover the 30 MHz to 250 MHz range for the lowest measurement uncertainty.

Some antenna manufacturers add an unsymmetrical crosspiece to the bicohnical elements in order to solve the inherent dip at the upper frequency response. Our solution is a simple ferrite around the center post of the elements, thus eliminating changing the symmetry of the antenna. The superior symmetry of the SAS-540 biconical antenna meets the ANSI C63.5-2017 symmetry requirements.

  • SAS-540 Antenna Balun
  • 2 removeable rigid elements
  • ABC-B, Balun Clamp with 1/4-20 thread
  • Antenna Calibration Manual

* Calibration data and certificate at 1, 3 and 10 meter horizontal polarity included
