Standard Gain Horns
-
Standard gain horns can be used to experimentally determine the gain of other antennas by using the substitution method. The standard gain horn and the antenna under test are alternately connected to a well matched detector system in order to compare their relative power levels. The power level difference is then added to the appropriate level of the calibration curve to determine the absolute gain of the antenna under test.View more Standard Gain Horn Antennas

Frequency Converter
-
A frequency converter, also known as a frequency changer, is a device that takes incoming power, normally 50 or 60 Hz and converts it to 400 Hz output power. Different types of power frequency converters exist, specifically, there are both rotary frequency converters and solid state frequency converters. Rotary frequency converters use electrical energy to drive a motor. Solid state frequency converters take incoming alternating current (AC) and converts it to direct current (DC).
