My foreign correspondant sent me pictures of the inside of La Fontenna today. The plastic case is sealed somehow without glue, so it is probably done ultrasonicaly. This one was opened with a small electric craft saw.
The antenna inside is simply a cheap printed circuit board suspended over a thin metal reflector. I doubt the La Fontenna is priced fairly at $20.00 + shipping (but perhaps not so bad at $2 + $5 shipping).
