*Standard conditions for average power rating: ambient temperature 40° C (104° F); inner conductor temperature 102° C (216° F); dry air; sea level atmospheric pressure; VSWR 1.0.
These values represent ideal conditions. We recommend that these ratings be applied conservatively to accommodate changes that may occur throughout the lifetime of the system. For example, at FM (88 - 108 MHz), we recommend average power limits of 15 kW for 1-5/8" line, 40 kW for 3-1/8", 80 kW for 4-1/16", and 160 kW for 6-1/8" on components.
