The well-kown EGIS-Rotor has an analog
input (AGC) for signal-strength dependent positioning optimization (Auto-Tracking).
This feature is essential for tracking
stellites in inclined orbit positions.
Such satellites are inclined in higher
Therefore a fixed antenna would deliver
a fluctuating signal quality over the time.
Only an additional information like
the the already mentioned AGC-signal always guarantees the best available signal
quality. The antenna will follow the satellites position automatically (Auto Tracking).
In the days of analog satellite-TV
many satellite receivers were able to deliver such a signal strength dependent
voltage - the so-called AGC output.
This valuable feature is lost with
the new generation of digital satellite receivers.
We can now offer a special model
of the SpectraBox SAT DX which has an additional signal strength dependent output.
Operating the SpectraBox in Zero-Scan
mode (0MHz/DIV) the device works like a receiver tuned to a fixed frequency.
This mode generates an optimum AGC
voltage for the EGIS-Rotor.
Together with the Auto
Resume firmware this model is especially optimized for EGIS-Rotor applications.
This model is also available with
the standard DX firmware on request.
