Adam, That’s what I was thinking also. That would be handy

You can further calculate based on the vertical beamwidth where the outer edge of the -3db coverage circle would land, and where the inner edge would land. Then you can attempt to visualize it. I feel like somebody once linked to an online map tool that would show you a simple visualization of where your sector would cover. I can't think of who or when now. Trig? Tangent? How far out do you want to focus the main lobe? Take the tower height, divided by that distance (both in the same units) and do the arctan of that. So if the tower was 200 feet, and you want to target a spot 2 miles away, arctan(200/10560)=1 degree From: Paul McCall via Af<mailto:[email protected]> Sent: Tuesday, October 14, 2014 8:13 AM To: [email protected]<mailto:[email protected]> Subject: [AFMUG] Downtilt tool We have upgraded a bunch of towers to ePMP (2.4) are finding we are going to really be more exacting with our downtilts to avoid spectrum overlap… more than we did with 100 series, because of the SNR requirements. I assume 2.4 450 would have similar requirements. So, I want to map out my down-tilt plans . Is there a good online tool for this? Paul McCall, Pres.
