I have done relative FS measurements (single point) at a distance of 60Km and can report that the CFA antenna is NOT working as the inventors say it will. The signal (giving all advantage to the CFA) is about 8dB down on similar standard antenna radiating stations. The facts (and these are not disputed by anyone - only ignored) are: - that the antenna was designed, constructed, tuned and re-tuned by one of the inventors. (No faulty installation one would have to assume). - the station power had to be reduced from its allowed 400W to 200W due to it interfering with nearby services. (CFA is supposed to be an antenna with little near-field interaction). - the station owners reconfigured the antenna to be fed as a standard short fat monopole because they obtained an increased FS with configuration as against the "superior" CFA. - the station is in the expensive process of moving their transmitting site elsewhere to use a standard antenna and is offering the CFA antenna to any sucker - sorry, buyer. CFA - miraculous? Certainly, unfortunately I don't believe in miracles - only repeatable measurements :-) 73s Steve Olney (VK2ZTO/AXSO - QF56IK : Lat -33 34 07, Long +150 44 40) ============================================= HomePage URLs: http://www.qsl.net/vk2zto http://www.zeta.org.au/~ollaneg Containing:- Laser Comms DX LF Experimentation Amateur Radio Astronomy =============================================
