Hi:

<< A 30% tuner loss is huge and would be dissipating 500W of a 1500 watt
input in a closed space. That wouldn't take long to set it on fire
internally, and would quickly make it too hot to touch.  >>


  I think tuner losses are being exaggerated here, tuners have only

small resistance's and almost all reactance which are loss less.

  I have never heard of a blower or fan cooled tuner, even a

50,000 watt tuner (50 Ohms in and 100 or 200 Ohms out) at .545 - 1,600

mHz with a reactive antenna (under 90 degrees) do not run hot or need cooling.

  I never heard of one.
