1. The power that can be handled will be a function of the size of the center conductor. The majority of
the heat flow will be via conduction. The weak point is the coax portion. The waveguide portion is
capable of higher power. These numbers are assuming an ambient temperature of 25 degrees
centigrade and an altitude of sea level. Higher ambient temperatures and altitude would degrade
power-handling capability.
