Well, Richard, tho in jest, serves purpose, that even with 30 watts lost on
surface of a balun , (or any other surface, for thatr matter), that by doubleing the size of the SURFACE, that it would take something like 4 TIMES as much heat to destroy it. For the same reason that a transistor, in the size of a micron will vaporize with a slight static discharge , doesn't necessarily mean that a POWER transistor will even feel a hickup, if it takes you 30 minutes with a 100 watt soldering iron trying to get solder on the leads! For the same reason , have 50 ohm coaxial resistor that fits in a reducer for rg-174, to a SO-239, that would probably crack, with the heat, and meantime also have a resistor, 1/3 the size, but made to mount on a heat sink, that will dissipate 100 watts all day! (also made as a 50 ohm load-- same devices, but different uses-- Jim Hi Jim, How close is anything to your flesh when you are holding it? Are you still holding it, if it were 2 times further away? 73's Richard Clark, KB7QHC |
