The toughest part of adding the N connectors was to get a pair of short

I will shortly repackage my nano with N connectors. I have found a couple of bulkhead types in my junkbox. They are for 1/2" coax, but can be adapted for some 1/4" PTFE coax from the same source :)
I want to use a diecast box (e,g, Hammond) to house the nano if possible.
Although the shells of both SMA connectors on the nano are shown connected to ground on the schematic, they appear to be soldered to separate areas of ground plane on the component side of the board.
I see from your pictures that the shells of both the N bulkhead connectors are connected to each other via the the aluminium chassis.
Have you noticed any deleterious effects as a result of mounting them in this way?
Other posters have isolated the shells of the bulkhead connectors from each other, either by mounting on an insulating panel, or by cutting separate lands on single sided pcb material.
Has anyone got any information on which way to go with this before I start cutting metal?
