[QUOTE="moonbase, post: 1073874, member: 178786"] Continuing on with the scan results for the various LNB's I have attached two more pictures below. The first picture is the chart for high band Horizontal polarity (yesterdays chart was Vertical polarity). The second picture is a feeble attempt to analyse the H and V high band scan results. In the analysis table I took the mean (average) of the signal levels for the 4 x LNB's per frequency and then calculated the deviation from the mean per frequency and LNB. Finally, in the bottom row of the table is the average of the deviation from the means per LNB. Conclusions: 1. All LNB's performed to about the same level, there was very little difference. 2. The test was a waste of time, the Precision 2.0m dish is too large and gathers too much signal from 0.8 West to show any weakness in the LNB's 3. If I decide to waste ony more time on this half baked project I need to use a smaller dish on a more fringe satellite. :-ohmy [/QUOTE]
