I would also favor smaller connectors/thinner coax to the boards on Atlas
too.
Less strain on the cards and -sockets.

I also would favor some separate antenna connection bracket:
- change from thinner (internal) to thicker (outside) coax and -connectors
- Antenna change over(RXTX) relay? Multiple antenna's? Splitter(s) (dual
receiver)?
- Protection
- Earthing
