Interesting- what price band will these newer models be in?

Is there a UK-approved system?  What frequency does it operate at?

This one puzzles me... the RF Solutions units are type-approved in the UK
(MPT1340), so wouldn't require any further testing, as long as the antenna
is constructed within the simple limits shown in the data sheets.  Any
commercial product will require EMC testing to get it's CE mark, so I don't
understand the problem- is this purely as US issue?

I thought others on the list might have similar questions...
