RFS Radio Link Antennas Survival and operational windspeed, definition Antennas withstand specified survival windspeed without any permanent damage ! Antenna axis deflection is less than one third of half-power beam width at operatio n windspeed ! Half-power beamwidth (HPBW) or 3dB-beamwidth: The angle, relative to the main beam axis, between the two directions at which the measured co-polar pattern is 3 dB below the value on the main beam axis. -3.0 dB Half-power beamwidth (3 dB-width)
