Parallel power supply of the rotary antenna motor
The IQmonitor program allows you to customize your receiving installation in the best possible way. To do this, there are tools for accurately measuring the signal level and SNR, the dynamic spectrum of transponders of both polarizations at once in real time, measuring the nonlinearity of the amplitude-frequency characteristic (AFC) of the installation and correcting its unevenness in RF spectra.
And for installation with an antenna on a polar motor suspension, it is possible to take the antenna pattern and determine the actual width of the main lobe of the pattern and the actual gain at different frequencies.
Unfortunately, the motor suspension consumes (especially in the cold season during start-up) a large (up to 0.5 - 0.7A) current, and you have to install it immediately after the drop cable to the receiver (PCI card input). In this case, the motor is connected in series with the LNB both by direct current and by a microwave signal. This leads to the formation of standing waves in the cable and a strong distortion of the overall frequency response of the receiving installation and, as a result, a decrease in its sensitivity.
