The CFA antenna is made by Hately Antenna Technology (GM3HAT). Every
month for many years now the RSGB has carried an advertisment for
this company. (until May, when the advertisment said they were moving
QTH and don't try and contact them until further notice)
One outstanding characteristic of this antenna is the lack of
information on it - after all these years.
The other characteristic is the lack of comparitive test (review)
information on it - after all these years.
The Wireless World (now Electronics World + Wireless World) did
several articles on the CFA but there was never enough information to
duplicate it. Finally an article 'CFA - RIP' appeared in May 1993 (I
have a copy), where a test version of the CFA radiation was -23dB
relative to a reference dipole. However, the radiation level did not
vary as the phase angle (using the phasing unit) was changed,
therefore it was not performing as the theory said it should.
The <www.antennex.com> website promises information - at a price.
Has any one used a CFA (or knows of someone who has used one) on any band?
