The R20 is much "more" receiver than the R5. You should do a comparison of the specifications and features found on the Icom website. If you decide the R5 is all you need it may be worth waiting a bit longer for the IC-R6 to become available. It has a number of improvements over the current R5.
Now the question arises about 1.3 Ghz and up. Usually such wideband rxs lose sensitivity dramatically when you get above 1 Ghz or so. It begs a question about what you are trying to hear. Who knows about the allocations in France, but here in the US, listening in this range requires more equipment than just a wide band receiver...73 Mike
