Hello,
to reply to your request of information: "One open question for you, what kind of antenna do you plan to use to cover both 433 and 868MHz with a single antenna matching circuitry ?"
I attach a picture of the antenna vertical sleeve @ lampda/4 whip for 433Mhz that we plan to use to cover both 433 and 868Mhz with a single antenna matching circuitry.
Best Regards
Vincent Rizzo
