The talk about dummy loads brought back a memory of the Heath 
Cantenna--an RF dummy load consisting of a Globar (noninductive) 
resistor in a gallon paint can filled with mineral oil with an 
attachment to a SO-239 "UHF" connector on top.  IIRC, it was literally 
capable of dissipating a full "gallon".

Kanthal Globar is still very much in business and does offer the 
resistors, if anyone wants to build such a unit for old times' sake.
