I think in theory that patent is then null and void!! However theory and practice are in theory the same, but in practice they rarely are :-)) Alan ----- Original Message ----- From: "John Rabson" <[email protected]> To: <[email protected]> Sent: Monday, August 22, 2011 4:48 PM Subject: Re: LF: Re: Re: Ferrite wideband antennas? >From an engineering point of view, a scientific theory does not have to be true. It just has to be useful. That is, it enables us to build something to meet our needs and for an acceptable cost. For the FSL antenna to be taken seriously, we need one or more examples of successful implementations, preferably combined with a set of formulae from which we can construct devices to meet our requirements. The same applies (by the way) to the Cross Field Antenna. I have read the patent specification and I cannot see from that how to build something for 137 kHz, even though the inventor assured me it could be done. John F5VLF |
