Has anyone had success specifying a term such as 'RFI Free' when
dealing with a contractor? Whenever there is AC (or worse yet, square
waves) there is going to be SOME level of RFI, no? The question
becomes what level is acceptable for a particular installation. In my
case, if it's VLF/ELF noise or HF noise below the noise floor on
antennas some distance away, I don't really care. I can't, however,
provide a more specific acceptable level such as a particular maximum
field strength. Something like 'RFI Free' seems rather amorphous and
if I were a contractor, I'd be reluctant to accept such a term.
However, if my customer provided concrete criteria (such as a maximum
field strength) I might actually be able to get some specs from the
manufacturer and have some reasonable confidence that I can perform
the install in such a way as to meet my customer's needs.
Just curious if anyone has brought RFI issues up, in writing, with a
contractor and how that worked out.
