Most of the experimenters that published some design abandoned the projects. We can feel this because the CFAīs related articles disappeared there. There was several projects, for 160m, 80, 40m, etc but results was marginal. Mr. Kabbary, one of the developers, never explained in details the magic touch to make this antenna works as pointing vector synthethizer. Every broadcaster that hire Kabbaryīs company to install CFAs abandoned the barrel somewhere on itīs warehouses (Germany, San Remo radio, Australia). Here in Brazil, Eng. Damiani brought one for a BC station thatīs 45Km from my house. Last reports says that they halt the project for a while, waiting for Mr. Kabbary visit, accomplished by his "magic touch". Still a controversy antenna anyway, with itīs looog wire feeders (radiators?). The NEC simulations shows that thereīs a short monopole. Only this. Australia installation suggest that the building structure acted as part of the radiating structure ... Other more controlled prototyping showed the same inefficiency ... Anyway ... CFA didnīt show yet itīs real value or - at least - as a pointing vector synthethizer. 73 Marcus, PY3CRX/PY2PLL GG66rf http://py.qsl.br
