With symmetrical horns it feels pretty cut and dry in regards to what azimuth to point them to as well as downtilt.
With asymmetrical horns however it feels, at least to me, a little more involved. For these, since the elevation beamwidth (I'll use the 90 degree horn as an example that has a 25 degree vertical beamwidth at the -6db mark), is the optimal process still the same? By that I mean, you take your 25 degree v-beam, divide it in half and then not exceed that margin on downtilt (in this example it would be 12.5 degrees)?
Or, are most people finding that keeping it at 0 the most successful option when modifying up/down tilt?
