[QUOTE="moonbase, post: 1063900, member: 178786"] Update 4: As a further point of interest I compared the SNR dB values between a Chinese C Band extended LNB and a Titanium LNBF for RHCP over the transponder range of 3900 MHz to 4200 MHz. The Chinese C Band extended LNB performed quite well against the Titanium LNBF for RHCP even though it is specified for 4500 MHz to 4800 MHz and was working on frequencies outside of its specification. The Chinese C Band extended LNB found signals as low as 3920 R. The C Band extended range was not scanned as there are no RHCP signals on 40.5W in that range. Equipment: Precision 2.0m prime focus dish AV-COMM polo pipe Chinese C Band Extended LNB attached to WR229 flange feed inserted into the polo pipe Titanium LNBF inserted directly into the polo pipe TBS 5925 USB device EBS Pro I have attached a picture of the scan comparison results below.
