Illustrative patterns — the main lobe is drawn on a 0 to −30 dB scale so its −3 dB width matches the published beamwidth. The back lobe, where shown, sits at the published front-to-back ratio. Sidelobes are not drawn. The exact plots are in the manufacturer PDF.

CALC.EIRPUse this gainEIRP / ERP

Pick a band. The gain comes from the table above. Add your transmit power and feed loss to get EIRP.

EIRP — Turn on JavaScript, or use the calculator link.

EIRP = TX power − loss + gain (dBi). ERP = EIRP − 2.15 dB. Open the full EIRP calculator →
