[Amps] PTFE fasteners or adhesive backed PTFE

[Neil Carr G0JHC]

Hi,

I'm in the process of making a "flapper" cap. I have been warned away from
using nylon screws to hold the PTFE in place and wonder what the sources are
for some PTFE fasteners or something else suitable for intense RF fields.
Even better, where do I get hold of adhesive backed PTFE? I haven't been
able to find any sources at first glace here in the UK.

 

Any suggestions?
