Way back in 1995, when the seminal book by Dr. Nick Begich and Jeane Manning Angels Don’t Play this HAARP was released, the putative inventor of HAARP, Dr. Bernard Eastlund, speculated that it is ‘entirely possible’ that such technology had already been miniaturized.
Aviation Week reported in 2008 that an airborne version of HAARP had been developed which is towed ‘behind a helicopter.’
The Sea-based X-band Radar (SBX) floating platform utilizes HAARP technology. Here is the Wikipedia listing:http://en.wikipedia.org/wiki/Sea-based_X-band_Radar
Little HAARPs modifying the local weather?
Scientists at the University of California Los Angeles and the High Power Auroral Stimulation (HIPAS) Observatory in Alaska have assembled a new generation of ionospheric heaters. This technology, known as ‘Hertzian antennas,’ can, “…match or exceed the peak power of the new HAARP system for a fraction of its cost.” Though most implementations are not capable of producing all of the complex, phased signals produced by facilities like HAARP at Gakona, Alaska or the antenna array at Jicamarca, Peru.
