Very definitely. There's a book now out of print called 'Radio Transmitters' by Brown of Marconi. He has quite a lot on parasitic suppression in big transmitters - and points out that the box can be a VHF resonant cavity (we're talking 50 -100kW transmitters or more) and resistive loading by having such a thing as an 80 ohm carbon resistor - Globar type, 12 inches long, 1 inch diameter -  with one end connected to the anode and the otehr in free space can privide enough resistive loading to kill a VHF parasitic. Or even several of them at various angles.
Rather out of our legal power levels.......
