A modified version of a low cost two-port TEM cell, with a 230 MHz highest operating frequency, has been realized. Two main aspects characterize this new version: the septum is now laterally sustained, and an easier soldering of the septum itself to the output terminals is obtained, by modifications of the septum ends and of the TEM cell terminations. A preliminary series of tests have been performed and the Voltage Standing Wave Ratio (VSWR) has been measured at different frequencies. Presently, a set-up with a VSWR lower than 1.35 in the whole operating frequency range has been realized.

Abstract
A modified version of a low cost two-port TEM cell, with a 230 MHz highest operating frequency, has been realized. Two main aspects characterize this new version: the septum is now laterally sustained, and an easier soldering of the septum itself to the output terminals is obtained, by modifications of the septum ends and of the TEM cell terminations. A preliminary series of tests have been performed and the Voltage Standing Wave Ratio (VSWR) has been measured at different frequencies. Presently, a set-up with a VSWR lower than 1.35 in the whole operating frequency range has been realized.
