Hi Luc,
The PES hasn't been around for a long time, almost 20 years. I don't have manuals for this anymore and memory fades but the recive range is probably 11.7 to 12.2 Ghz and the transmit range is probably 14.0 to 14.5 Mhz. I think the receive IF range is the standard 950-1450 Mhz range but Hughes used a proprietory transmit IF. Voltage was supplied on the IFL cable using bias T's internal to the "InDoorUnit". It was also customary to inject the 10 MHz PLL reference on the TX and sometimes RX IFL cable(s). The unit on eBay is the second generation "OutDoorUnit" manufactured by NEC of Japan for Hughes. The pointing output supplied a DC voltage proportional to signal strength. This unit will require allot of surgery to be useful 10 Ghz. ...de Howie AB2S
