Also, I think Bob Brunniga... has documented that 15 deg fixed is the best overall el setting.
Yep, that puts the main beam on the horizon where you need it most and where satellties spend over 70% of their time. Even at 15 degrees, you still are within 1 dB of max gain on the horizon. That same amount of gain covers up to 30 degree too. And anything above 30 degrees is 6 to 10 dB CLOSER and does not need much gain. Above 70 degres there begins to be a null, but satellites will be in that null less than 1% of the overall contact time.
