2/ Actual attenuation of waveguides may be considerable greater depending upon operating frequency and temperature. Typical resistivities of materials (at 20° C): aluminum alloy (6061) = 4.0 microhms-cm; copper alloy (brass) = 3.9 microhms-cm; copper -1.77 microhm -cm; silver alloy (coin silver) = 2.03 microhm-cm.
3/ Actual power handling capability of waveguides may be considerable less depending upon waveguide temperature, altitude, operating frequency, etc. The tabulated values were calculated based upon the E field produced breakdown in a nonpressurized air dielectric waveguide under continuous wave (CW) conditions. The breakdown strength of air was considered to be 15000 volts per centimeter, corner radii considered.
