The ANB-0230S is a bi-conical dipole antenna is designed for Shielding Effectiveness compliance testing in accordance with IEEE 299 test standards. The ruggedized aluminium - cage dipole construction is precision manufactured and tested to conform to the requirements of the standards. An integrated low loss 200:50Ω bal-un, inside the antenna ensures a good impedance match between the antenna elements and the end connector, over a wide range of frequencies.
