Antenna Downtilt Calculator

Calculate main lobe impact and ground footprint with an interactive RF visual.

Back to Home

Inputs

Set basic RF parameters:

Uses site coordinates + azimuth and current distance value as profile length.

Uses antenna pattern + selected propagation model assumptions + RSRP max radius.

Ready to calculate.

Main Lobe Impact Point

-

Ground intersection of central lobe.

Footprint Coverage

-

Ground span covered by lobe (using configured vertical beamwidth).

Estimated RSRP

Disabled

Enable "RSRP Simulation" to compute a received level at max radius.

Assumption: Vertical beamwidth defaults to 5.8 deg, but you can modify it.

Sector Map (OSM)

Sector built from site coordinates, azimuth, horizontal beamwidth, and auto-adjusted distance.

Waiting for valid site coordinate and azimuth.
