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.
