From time to time an amateur builds and sells them here but currently there is none for sale.
I hope this helps.

Hello again, Does anyone know of a U.K. commercial source for this antenna. I know that there are a number of web sites out there with instructions on how to make this antenna but for a number of reasons I need to purchase one ready made?
