Not necessarily. There is a large corpus of knowledge available on
how to build vapor cells standards and what is a good idea and what
isn't. Most of it is documented in papers of the PTTI, EFTF and IFCS.
The former two are freely available (for PTTI until 2010, but that
should be good enough). Getting access to those papers behind a
paywall, you only need to know someone with access to a university.
(not for PTTI post 2010 though, ION has quite anal access rules)

Additionally, the people in the time and frequeny community are very
open to discussion and exchange of knowledge. You can almost always
just walk up to someone and ask questions with a high chance of getting
not only answers but help in how to proceede. 

Tapping into this knowhow would avoid the need to try out the whole
solution space and concentrate on the few parts that are unkown or
not well enough understood and optimize those. And by doing so safe
a lot of money.
