[QUOTE="Simba27, post: 87411, member: 182734"] I haven't given up on the idea. It's still in the back of my mind, I just haven't had the time to dedicate to it. I want the results to be scientifically valid with no room for doubt. The experiment plan is as follows: 1) Set up a test dish and a control dish. Fit each with an LNB. 2) Using the same receiver and cable (swapping it between LNBs), align both dishes for maximum signal on the same satellite. It's important to spend time at this stage to ensure the absolute maximum signal. 3) Write down the signal strengths for both dishes on various transponders. Perhaps High-Horizontal, Low-Horizonal, High-Vertical, Low-Vertical (not that it should make a difference). 4) Work out how much better or worse the test dish is compared to the control dish. Take the ratio of signal(test) to signal(control) for each transponder. 5) Clean the all the dirt, rust and algae off the test dish. 6) Repeat steps 2, 3 & 4. Calculate any improvement or loss. 7) Fill in holes on work dish. 8) Repeat steps 2, 3 & 4. Calculate any improvement or loss.

Measuring relative to a control dish will ensure that any deviations due to weather, transmission strength or dish positioning are eliminated. The LNB's don't have to be the same because they are constant between measurements. To do it properly will need a whole day of my time, and I'm way too busy at the moment.
