Re: Shielding material other than pcb
In the past, I built a 'naughty' shortwave transmitter into a pair of gallon-size Castrol GTX oil-cans. The metal was rather flimsy so I used some wooden battens to reinforce the area round the modulation-transformer.
And I have to mention the Heath "Cantenna" RF dummy-load built into a paint-can.
One 'screening material' worthy of mention is the self-adhesive copper strip used by modelmakers who want to 'fake' stained-glass windows. Something similar is available from garden-centres, where it's sold as 'copper slug-barrier' [apparently the mucilaginous molluscs dislike crawling across copper].
If you want a ventilated screened enclosure [for exampe to house a valve PA stage or a VFO] then places like Halfords and B&Q sell perforated-stainless-steel mesh sheets.
